NOVEMBER 2, 1905.
The 199th regular meeting was held at the residence of Dr.
. Ch. Wardell Stiles, 1412 Hopkins street, N. W., with the
president, Mr. Banks, in the chair. The following were pres-
oy ent: Messrs. Ashmead, Banks, Barber, Burke, Busck, Caudell,
eee Dyar, Gill, Girault, Heidemann, Hopkins, Knab, Marlatt,
Morris, Patten, Quaintance, Schwarz, Scott, Stiles, Titus,
Ulke, Webb, and Webster, members, and Messrs. F. W. God-
ing, E. F. Phillips, and O. W. Barrett, visitors.
Doctor Stiles presented an explanation of the system of card
catalogues in use in the laboratories of the U.S. Public Health
and Marine Hospital Service, illustrating his remarks with the —
various types of cards used in the catalogues. Some general
discussion regarding the system and also regarding the com-
pilation of a list of all described genera of the world was
- participated in by members present.
—Doctor Ashmead spoke of a new and remarkable genus of
: Chalcididz, parasitic on mantid eggs, that had been recently
received from Father Robert Brown, of Manila, P. I. He
noted the fact that so many groups that have no spines on the i
thorax in our country are represented in the tropics by genera ne
_ provided with spines. | | ert
. _~—Mr. Caudell exhibited specimens of the various species of
the true katydids (Cyrtophylli) from North America, com-
prising, in his opinion, three genera and six species. He had ex-
Pete amined about 100 specimens and found many striking charac-
Bas ters separating the species. In answer toa query regarding the —
Be 2 ne
2 ENTOMOLOGICAL SOCIETY
breeding habits, Mr. Caudell stated that the species, so far
as known, live in trees, rarely forsaking the tops and then
only, apparently, for the purpose of oviposition. One species
has been found ovipositing at night in the bark of a tree near
the ground. In one species of this group the female has the
power of stridulation—something unknown for this sex in
any other group of Orthoptera. Some considerable discussion
regarding the ability or non-ability of the insects to fly took
place. So far, there is no absolute case known of the insects
flying, but some of the members believed that they do fly at
times and probably at the mating period.
—Doctor Dyar exhibited the recently issued second volume
of Packard’s “ Monograph of the Bombycine Moths of America
North of Mexico,” published as a memoir of the National
Academy of Sciences. This volume was edited by Samuel
Henshaw after Professor Packard’s death and treats only
of the Ceratocampide. A remarkable feature of the plates
noted by Doctor Dyar is that all the larve are figured upside
down. Larve in this group always cling to the underside of
the twig or leaf upon which they are feeding.
—Doctor Gill made a few remarks on the present erroneous
use by several authors of the termination oidea for families.
Its well-established application as a termination for super-
family groups should preclude the use for any other group.
_—Mr. Busck exhibited specimens of a peculiar large antho-
myiid fly (Mydea pici Macq.) which is parasitic on small birds
in Santo Domingo, W. I. The eggs are laid on the young
nestlings and the larva develops in a sac on the head or on
the wing of the bird, which, when of small size, is sometimes
curiously malformed by the large parasite. The species was
described in 1853? from a specimen bred from the wing of
a young pigeon in Santo Domingo. The present specimens
were bred from a young specimen of the small palm-chat, Dulus
dominicus L., which was shot on September 8. The larva left
the bird the same day, burrowed into earth provided for it in a
box, and made a cocoon of particles of earth glued ot by
a glistening white excretion.
* Ann. Soc. Ent. France, p. 659, Pl. xx, Fig. 1.
OF WASHINGTON. 3
The fly issued on September 18. The species is evidently
common, the number of small birds affected in that locality
amounting to nearly 90 per cent, but the injury is not neces-
sarily fatal and old birds often showed the shriveled up
larval sac, indicating infestation in earlier life. |
—RMr. Busck spoke also on the presence in Trinidad of the
bot-fly that attacks human beings. He stated that many of
the coolies are infested with these larve.
Mr. Barrett spoke of an experience he had had with this
bot-fly while in Mexico, and has since furnished the following
abstract of his remarks:
NOTES ON THE MAN-INFESTING BOT IN MEXICO.
By O. W. BARRETT.
[Author's Abstract. |
- Regarding his experience with the so-called Dermatobia
hominis, the writer would say that he personally knew of its
wide occurrence in the Tuxtla district of Vera Cruz, Mexico,
a locality about seventy-five miles southeast of the city of
Vera Cruz; it was in the year 1897 when he visited that sec-
tion and “ took the notes.”
There are at least three theories for the entrance of the
larva beneath the skin. The one that seems most probable is
that the newly-hatched grub can crawl some little distance
before beginning to burrow. ‘The first symptoms of the
attack are intense itching and burning at the mouth of the
burrow, which is greatly swollen and reddened. At about
the second week of the existence of the larva inside the burrow
sharp pains are felt as if nerves were being severed. At the
second week, also, begins a slight exudation of serum. At-
tempts to dislocate the larva by physical means are unavailing
on account of the retroverted setz along the slender caudal
portion of the insect. The burrow eventually becomes of
some 10 to 20 millimeters in depth, with an opening of I to 2
millimeters. The larva is of a dead white color, with dark
brown or blackish setz.
Badly parasitized individuals are likely to suffer from the
septic effects of larvae crushed within the burrows, and of
course the pain and worry have a bad psychological effect.
The smothering method of killing the larva is one of the
most convenient and successful; fresh “chicle” (Achras
+ ENTOMOLOGICAL SOCIETY
sapota gum) or court plaster is used. Cigarette ashes are
sometimes worked into the larva sac but tend to increase the
irritation and seldom kill the insect.
‘Mr. Titus mentioned that Mr. R. J. Crew, when collecting
in British Guiana, found that he had one of these larve in
the calf of his leg, but was unable to breed it out on account
of the severe pain and probability of blood-poisoning fol-
lowing the attack. He had the larva removed after reaching
his home in Canada. Mr. Knab noted that on his recent trip
to Central America and Mexico he had seen several cases
where the larva was present in human beings. Doctor Stiles
stated that this species was known to occur in hogs, dogs, and
monkeys on the Isthmus of Panama.
—Dr. F. W. Goding, U. S. Consul at Newcastle, New South
Wales, was introduced and spoke several minutes on the
entomological conditions in Australasia. He stated, among
other things, that the museums in those colonies would be glad
to send their specimens to this country and get them worked up.
—Doctor Hopkins then presented the following paper and
exhibited specimens and work of several of the species treated :
BARKBEETLE DEPREDATIONS OF SOME FIFTY YEARS
AGO IN THE PIKES PEAK REGION OF
COLORADO.
By A. D. Hopxtns, Ph.D.
In the course of my studies of forest insects in different sec-
tions of the Rocky Mountain region during the past six years,
I have been specially interested in the frequent evidences of
wide-spread depredations by barkbeetles, found on old, dead,
and fallen timber. During investigations last month (October,
1905) in the Pikes Peak region of Colorado much additional
evidence was found on old, dead, standing, and felled trees of
the work of the Black Hills beetle (Dendroctonus ponderose
Hopk.) on pine, the spruce-destroying beetle (D. piceaperda
Hopk.) on Engelmann spruce, and the Douglas spruce Den-
droctonus (D. pseudotsuge Hopk.) on Douglas spruce, indicat-
ing that all of these species have been present and destructive to
living timber in this region for from thirty to fifty years. The
number and distribution of such old beetle-marked trees indi-

cate that very extensive depredations have been wrought by
these barkbeetles in the Pikes Peak region within the past
century, and present conditions also indicate that a large per
cent of the vast destruction of tithber heretofore attributed to
fire was primarily due to the work of these insects.
This was particularly striking on the southern slopes Of
Pikes Peak, at an altitude of about 10,000 feet, where nearly
all of the timber had been killed some fifty years ago. In
the fragmentary patches of living timber old felled trunks of
a primitive matured forest of Engelmann spruce were found
thickly covering the ground. On the weatherbeaten surface
of these logs the characteristic markings of the galleries of
Dendroctonus piceaperda were so common as to leave little
doubt that the trees had been killed by a destructive invasion
of this species—indeed quite conclusive evidence of this is
found in the presence of dried resin in the grooves, which
would not be found there if the trees had been attacked after
they were dying from other causes.
This additional evidence, together with the known devas-
tating work of this class of insects, makes it clear to me that
there has been a most intimate interrelation of destructive
barkbeetles and forest fires in the denudation of the vast areas
of once heavily forested lands in the Rocky Mountain region,
and that in very many cases the insects have first killed the
timber, and the fire has then followed, leaving the charred
trunks and logs as apparent proof that the fire alone was
responsible.
DECEMBER 7, 1905.
The 2ooth regular meeting was held at the residence of Mr.
C. L. Marlatt, 1440 Massachusetts avenue, N. W., the presi-
dent, Mr. Banks, occupying the chair. . The following persons
were present: Messrs. Ashmead, Banks, Barber, Barrett,
Burke, Busck, Casey, Caudell, Couden, Currie, Doolittle, Dyar,
Fairchild, Fiske, Gill, Heidemann, Hopkins, Howard, Hunter,
Knab, Marlatt, Patten, Piper, Quaintance, Schwarz, Stiles,
Titus, Uhler, Webb, and Webster, members, and Messrs.
Douglas H. Clemons, E. R. Sasscer, George R. Stetson, and
J. F. Strauss, visitors. The minutes of the November meeting
were read and approved.
Three persons were elected to active membership, namely,
Mr. Jasper M. Lawford, of 718 North Howard street, Balti-
6 ENTOMOLOGICAL SOCIETY
more, Md.; Mr. O. W. Barrett, of the Bureau of Plant In-
dustry, U. S. Dept. of Agriculture; and Dr. E. F. Phillips, of
the Bureau of Entomology, U. S. Dept. of Agriculture.
The resignation from membership of Mr. C. L. Pollard was
presented and accepted.
By vote of the Society the whole matter of the future publi-
cation of the PROCEEDINGS OF THE ENTOMOLOGICAL SOCIETY
OF WASHINGTON was referred to the Publication Committee
with instructions to report at the next regular meeting of the
Society. ~
The following officers were elected for the year 1906: Pres-
ident, Nathan Banks; First Vice-president, A. D. Hopkins;
Second Vice-president, O. Heidemann; Recording Secretary,
Rolla P. Currie; Corresponding Secretary, E. S. G.’ Titus;
Treasurer, J. D. Patten; additional members of the Executive
Committee: H. G. Dyar, L. O. Howard, and C. L. Marlatt.
—Dr. Howard gave an account of his trip to Europe during
the past summer, the object of which was to secure, if possible,
for introduction into the United States, the parasitic and pre-
daceous enemies of the gypsy moth (Porthetria dispar L.) and
brown-tail moth (Euproctis chrysorrhea L.).* Among the
localities visited were the Azores Islands, Gibraltar, Naples,
Florence, Milan, Vienna, Budapesth, Dresden, Pams, etc.
Many photographs illustrating the trip were exhibited. Among
the insects secured as of possible value in destroying the gypsy
and brown-tail moths he especially mentioned the fly Tachina
larvarum L.. He also spoke especially of the difficulty of im-
porting the European species of Calosoma.
In discussing Dr. Howard’s communication Mr. Schwarz
reviewed the little which is known of the biology of the
Calosomas of Europe. It seems pretty well established that
there is but one annual generation. He said that too much
must not be expected of these beetles as gypsy and brown-tail
moth destroyers. Nothing appears to be known of the hiberna-
* Doctor Howard has published an account of this trip in the Year- —
book of the U. S. Department of Agriculture for 1905 under the title
“The Gypsy and Brown-tail Moths and their European Parasites”;

tion of the species of Calosoma, although the probabilities are
that the beetles winter as full-grown larve in the ground. In
his opinion the Calosomas of the United States do not have
the climbing habit so well developed as do the European
species.
Mr. Busck stated that in May, 1898, he packed up a num-
ber of living adult specimens of Calosoma scrutator Fab., col-
lected at the electric lights at the Capitol, and gave them as
a curiosity to Dr. Yngve Sjostedt who had been visiting in
the United States at the time. They were placed in a tin box
with a large nest of living half-grown Hyphantria larve for
food and were shipped by express to Dr. Sjostedt’s steamer in
New York. In a letter a month later Dr. Sjostedt wrote that
the great majority of the beetles had come over in perfect
condition and that he had exhibited them alive at the fol-
lowing meeting of the Stockholm Entomological Society.
From this experience it was reasonable to infer that European
Calosomas could be introduced into the United States.
Mr. Schwarz said that carabid larve of various species had
been successfully reared on a diet of raw meat by the late
Prof. F. G. Schaupp, of Brooklyn, N. Y. Doctor Hopkins
stated that he had found Calosoma beetles of two species very
abundant high up in trees badly defoliated by what was sup-
posed to be canker-worms, in Greenbriar County, W. Va. Mr.
Knab said that he had found adults of Calosoma calidum Fab.
—undoubtedly hibernated individuals—in drift and under
stones near Springfield, Mass., in the early spring. Mr.
Hunter spoke on the common occurrence of Calosoma scru-
tator Fab. in the Texas cotton fields, where there are no trees
near. Mr. Titus said that he had collected Calosomas under
stones in Colorado, at altitudes of from 6,000 to 8,000 feet,
during December and January. Mr. Schwarz spoke on the
spread in North America of Carabus nemoralis Muell., a
European species which is now quite common around Boston.
He believed that the introduction of large carabid beetles into
the United States is quite feasible. Doctor Howard said that
he had met with great conflict of evidence among the European
naturalists as to the hibernation of Calosoma, and stated that
8 ENTOMOLOGICAL SOCIETY
ever since autumn entomologists all over Europe had been
hunting for Calosoma to send to America. Up to the present
time, however, not a single specimen had been found.
Doctor Hopkins said that this effort to introduce parasites
of the gypy moth and brown-tail moth was a most important
one, and he thought it would be well to endeavor to introduce
the parasites of other defoliating caterpillars also.
—Mr. Banks then presented the following paper:
NOTES ON PTERONARCYS, A GENUS OF PERLIDZE.
By NATHAN BANKS.
The genus Pteronarcys comprises the largest of our Perlide.
Its members have long attracted attention, since the adult in-
sects retain, in a more or less perfect condition, the gills which
served them as organs of respiration during their early stages
in the water. A similar condition, however, is now known to
exist in various other stone-flies. All but one of the six or.
seven described species of this genus occur in the United
States, the single exception being from Siberia. The best
characters for the separation of the species lie in the structure
of the ninth ventral segment in the male, and of the eighth
ventral segment in the female. Lately I had an opportunity
of examining the collection of the late Doctor Hagen in the
Museum of Comparative Zoology, Cambridge, Mass., and
now, in going over my own collection, I find that I have a new
species, the most distinct one in tha genus. It may be described
as follows:
Pteronarcys spinosa, n. sp.
Black, scars of head reddish, a narrow reddish stripe on middle of
pronotum, ventral segments of abdomen margined with yellowish.
Wings not very long; venation dark brown,
rather dense; a dark cloud over the first cross-
vein between the radial sector and the radius,
and extending up into the costal area; another
dark cloud near middle of wing and basad of the
first one; hind wings with the costal spot, but
without the interior one; an elongate black spot
near basal costal part of forewings. Female
with the 8th ventral segment evenly rounded,
and with two long, divaricate, spine-like processes from the middle
(fig. 1). Male with the oth ventral segment broadly truncate at tip, not

tinctly separated from the sides by nearly parallel carine.

One pair from Oregon, from a Mr. Warren.
To show the position of this species in the genus, I have

and presented the following paper:
10 ENTOMOLOGICAL SOCIETY
ACCOUNT OF A NEW TINGITID.
By O. HEIDEMANN.
-Corythuca pergandei, n. sp. (fig. 2).
Smaller than the oak or sycamore tingitids. The net-like reticulation
of the surface yellowish, the areoles more or less translucent; across
the elytra are two brown bands, one at base and the other near apex,
the latter one sometimes only faintly colored; the membranous pronotal
margins also partly infuscated. Body black, except the margin of pro-
sternum, the humeral area, and the last two abdominal segments, which
are fulvous; very dark specimens have the abdomen almost entirely
black. The pronotal hood, which entirely covers the head, is of mod-
erate size, with the posterior part not very elevated; it is about as long
as the triangular portion of pronotum and its posterior globular part is
not broader than one of the membranous pronotal margins; it is
abruptly constricted at about the nriddle, from there tapering gradually
towards front and forming an apex which, viewed from the side, is
hook-like. The areoles of the globular por-
tion of the hood are quite large, hexagonal
or pentagonal, the others smaller and ir-
regular. Antenne slender, pilose, and pale
yellowish, sparsely beset with a few very
long, bristly hairs, the apical joint knobbed
at tip, usually darker in color; the third
one hardly more than twice the length
of the two basal joints taken together;
second joint shortest, half as long as the
first. The rostrum enclosed in the rostral
groove, which is rounded and closed be-
hind, reaches the base of the metasternum.
The membranous pronotal margins are
Fic. 2.—Corythuca pergan- bean-shaped and the surface is much

with the areoles nearly uniform in size.
Pronotal processes broadly triangular, deeply punctured at base and
irregularly reticulated towards the apex; the lateral margins only
raised anteriorly, having a few cells. Middle carina feebly elevated,
hardly one-half as high as the hood, rounding a little from its base and
slightly sinuated behind the middle to the tip; it has five or six cells,
sometimes one or two additional ones caused by a little cross-vein divid-
ing the middle cell, which is then somewhat embrowned. In some
specimens the carina often appears truncated. The elytra when closed
are very little longer than broad, rather subquadrate; lateral margins

nearly straight, the anterior and posterior angles broadly rounded;
edges of elytra and pronotal margins armed with short, white spines,
tipped with black; at the nervures of the hood and near the elevated
part of elytra there are also a few scattered spines. Sometimes speci-
mens have the armature a little stronger. Discoidal area irregularly
reticulated with four or five rows of areoles, tumidly elevated behind,
marked with a brownish spot; the subcostal is biseriate and the costal
area has three rows of hexagonal or pentagonal areoles, those on its
widest part, mostly at the inner side, very large; on the sutural area
before the apex are also a few large hexagonal areoles. Legs yellow-
ish, the tarsi darker at tip. Claspers of the male strongly curved, not
hairy.
Length 3.2 mm., width 1.6 mm.
Described from many specimens of both sexes. Some larval
forms were also examined. Washington, D: C., February 18,
1884, October 12, 1882 (Pergande), July 18, 1902; Bedford
Co., Pa., August 23, 1902; Front Royal, Va., September 10,
1903, May 29, 1904 (Heidemann) ; Springfield, Mass., August
29, 1902; Urbana, Ill., October 11, 1904 (Knab) ; Lawrence,
Kans. (Tucker).
Type (from Washington, D. C., g and 9).—No. 8302, U.
S. National Museum.
This new species is to be distinguished from Corythuca
ciliata Say, and from the species occurring on oak by the dif-
ferent shape of the pronotal hood, which is less elevated in
both of the latter, and by the fact that in these latter, also, the
adjoining middle carina is as high as the globular portion of
the hood. It is also distinct from Corythuca marmorata Uhler
in having the elytra not so much speckled with brownish mark-
ings; while Corythuca incurvata Uhler differs from it in the
great, abrupt height of the hood, and Corythuca juglandts
Fitch differs from it in the more inflated, globular part of the
same.
In one of the note-books of the Bureau of Entomology, Dept.
of Agriculture, there is a short account of this tingis by Mr.
Th. Pergande under number 2893, as follows:
October 12, 1882, February 18, 1884, found quite a number of Tingis
on lower side of leaves of different species of Alnus on the Agricultural
grounds of Washington, D. C. Mounted winged specimens, marked 2893,
and larve on slides 3/4/1.5.
No. 2945, November 5, 1882; found several specimens, larve and
adults of Tingis on lower side of leaves of Hazel. Mounted winged
ones, marked 2945, and larve on slide 3/1/56.
The U. S. National Museum also contains specimens of
this tingis, labeled as found on elm and crab-apple trees. I
12 ENTOMOLOGICAL SOCIETY
have taken specimens from the leaves of black alder as early
as May and late in September. The insect hibernates in the
adult stage under fallen leaves and in the crevices of the bark.
The eggs of this tingis, which I found on the black alder,
are shaped like the eggs of those known to be on oak and are
only a trifle larger; this insect has, also, the same habit of
depositing its eggs on the underside of the leaves, fastening
them to the surface, differing however in that it completely
hides them under the dense pubescence of the leaf, in the
axil which is formed by the main rib and its side branches.
In this way the eggs are entirely out of sight and well
protected.
Fic. 3.—Corythuca pergandei: Young larva or nymph at right, older nymph at left,

The larval forms (fig. 3) are quite similar to those of the
oak tingitid, except that the body appears to be less broad.
They are armed with the same kind of spines, which Dr. A.
W. Morrill in his excellent treatise on the immature stages
“of some tingitids* has termed “trumpet-shaped spines, type |
No. 1, type No. 2, and simple spines, type No. 3.” These
spines arise from elongated, thick protuberances, or from a
conical base, and are situated on the head, at the margins of
thorax, and on the dorsal part and sides of the abdominal

segments. But the larve of C. pergandei show some differ-
ences in their last two stages, in having also some spines
belonging to type No. 1, rounded at tip (fig. 3), not trumpet-
shaped, and more like those of the nymph of C. ciliata Say in
the first instar, according to Doctor Morrill. Besides there
appear in the last stage or pupal form some long, simple spines
of type No. 3, which are not pointed at the end, but slightly
inflated. Two very long spines of this latter shape rise from
the base of the head, and a few smaller ones from the abdomi-
nal segments, dorsally, near the margins. The antennz are
sparsely covered with simple spines and the legs with very
short ones. I take pleasure in naming this new species in
honor of Mr. Theodore Pergande, who was the first to take
notice of this species.
—Mr. Barrett showed several photographs taken by Mr.
Fairchild and himself, of bumblebees in the act of mating, and
presented the following notes:
NOTES ON THE COPULATION OF BOMBUS FERVIDUS.
By Davip FatrRcHILD AND O. W. BARRETT.
(Plate I.)
While walking across the nursery plats of the Arlington
Farm, about October 13, the writers noticed three individuals
of a species of Bombus clinging to a young cherry tree about
six inches above the surface of the ground. Upon close ex-
amination it was found that one male, apparently lifeless, was
in coitu with a female of the same color but slightly larger
size, and upon the back of the female another male was
actively endeavoring to copulate. The female clung tena-
ciously to the stalk and paid little attention to the maneuvers
of the male upon her back. The male im coitu was suspended
by the genitalia only, all the legs being held appressed to the
_. body and motionless. Upon irritation with a straw the latter
male evinced life only by buzzing of the wings. The male
not im coitu, which may be designated as male No. 2, was
quick to notice any interference in his actions by means of
the straw but could not be induced to leave the body of the
female.
Presumably copulation had continued for some little time
previous to the finding of the specimens and there was no
apparent tendency towards its cessation when the coitus was

interrupted forcibly, although so gently and gradually that
the female was not greatly disturbed. Male No. 1, immediately
after connection was broken, evinced a desire to leave the
female, showing no desire whatever to renew the relations.
Rapidly regaining activity he soon rose in the air and slowly
flew away. oe 3
Male No. 2 left the back of the female as soon as male No. 1
had disappeared, and stationing himself about fifty or seventy-
five millimeters directly in front of her began a series of com-
plex marches and short charges towards her. The female,
though loath to move, resisted these advances and when male
No. 2 continued to approach her she made a short charge
toward him, buzzing her wings and waving the prothoracic
legs threateningly. This procedure was repeated several times
until the female had succeeded in impressing male No. 2 with
the idea that further advances would be dangerous; she even
fiercely attacked the male once or twice as the result of his
-charges toward her. The female next evinced a desire for
flight and rose in the air once or twice but was struck back
upon the ground. Here she remained, apparently in a sullen
mood and scarcely responding to the straw irritations. Male
No. 2, noticing the female’s change of mood and probably
scenting trouble through outside circumstances, gradually lost
his interest in the case, though he remained close to the female
~ until the last..
Five photographs were taken, each showing the three insects
in situ. In No. I the female is clinging to a weed stem while
male No. I is suspended by the genitalia and male No. 2 is
clinging to the female.
_—Doctor Dyar presented for publication notes on the collec-
tions of mosquitoes made for Doctor Howard under the
auspices of the Carnegie Institution of Washington by Mr.
August Busck in the West Indies and by Mr. Frederick Knab
in western Central America. The results of both trips are
very satisfactory. Mr. Busck’s region proved richer in species,
as would be expected, the west coast of Central America being
more arid. .Many new larve were discovered; Doctor Dyar
exhibited sketches of 24 species not hitherto known from our
territory. Two of them have been previously described by
Goeldi from South America ; the others are new to us.
The wealth of aédid larve shown in these collections had
led Dr. Dyar to hope that some character might appear sepa-

CLASSIFICATION OF THE FORAGING AND DRIVER
ANTS, OR FAMILY DORYLIDZA, WITH A DE-
SCRIPTION OF THE GENUS
CTENOPYGA ASHM.
By Witt1aAm H. AsHMeEap, M.A., D.Sc.
In the Canadian Entomologist for November, 1905, pages
381 to 384, I gave a skeleton of a new arrangement of the
families, subfamilies, tribes, and genera of the Ants, or the
superfamily Formicoidea in which several new genera were
indicated. Among these was the genus Ctenopyga, from
Mexico, which I now describe and figure, after giving analyt-
ical tables for recognizing the three subfamilies, the tribes,
and the genera falling in each, according to the three sexes,
worker, female, and male, when known, taken from my forth-
coming classification of the Ants, or the superfamily Formi-
coidea.
Family XLIII. DORYLIDZE.
The ants belonging to this family are held together and
easily separated from those of other families by habits and by
peculiarities of structure, the females being nearly always wing-
less, the workers having the antenne inserted much farther
forward on the head, close to the anterior margin, and by
the genitalia of the males which differ widely from those of
other ants, the terminal ventral plate, or the hypopygium, being
broad and deeply semicircularly emarginated, forked or
bispined.
22 ENTOMOLOGICAL SOCIETY
It is this character which induces me to place the Acanthos-
tichinze in this family rather than in the family Poneride, al-
though otherwise, especially in the workers, they are apparently
just as closely allied to that family, where Forel and Emery
now place them.
The first species discovered, however, was a worker and
that was originally placed by Frederick Smith, of the British
Museum, in the Dorylid genus Typhlopone Westwood. Dr.
Gustav Mayr made Typhlopone serratula Smith the type of
his genus Acanthostichus, which is now known in all three
sexes, the female having been described and figured recently
by Professor Emery, who also at one time classified the genus
with the subfamily Dorylinz.
The three subfamilies may be recognized from the structural
characters made use of in the following table:

Subfamily II. DoryLinz.
This subfamily reaches its greatest development in Africa
where the genera and species are numerous, although a few
extend into Asia.
It may not occur in America, as the two American genera
placed here, namely Typhlopone Westwood and Cheliomyrmex
Mayr are unknown to me in nature and are placed here from
the description alone. I suspect that both may belong to the
Ecitonine. Sphinctomyrmex Mayr is also another doubtful
Doryline which I have not been able to see.
Two distinct tribes have been recognized from the males.

Africa is evidently the original home of this tribe, where
the genera and species are abundantly represented. Prof. C.
Emery, the eminent Italian myrmecologist, in his paper “ Die

fusion that existed in regard to the genera and species, and has

This subfamily is undoubtedly closely allied to the next

being similar to the dorylid type I prefer to retain it in this
group. |
Representatives are known in North America, 7. e. Texas,
Mexico, and Central America and in South America. The first
specimen I had seen of this curious group, Acanthostichus
kirbyi Emery, was kindly given to me by my friend, the emi-
nent French hymenopterologist, Mr. Ernest André, of Gray,
France. This has aided me very materially in working out
the new genus characterized below:

A NEW SPECIES OF THE CURCULIONID GENUS PARA-
PLINTHUS.
By W. F..Fisxe.
Paraplinthus shermani n. sp.
Length 6.8 mm.; color very dark brown, more or less tinged with
reddish; above sparsely clothed with elongate, yellowish scales, forming
obscure irregular markings on the elytra. Prothorax with sides evenly
rounded, convex above, median carina narrow, straight, sharply defined ;
surface above and on both sides with irregular, coarse, shining tuber-
cles; punctures of elytral striz sometimes separated with slightly ele-
vated tubercles; interspaces each with one row of tubercles, more
strongly developed on the alternate interspaces, which are also dis-
tinctly elevated.
Type.—No. 6370, U. S. National Museum.
Collected on Pisgah Ridge, Transylvania Co., N. C., at an
elevation of between 5,000 and 6,000 feet. Three others were
_ collected by the author at the same time. In the U. S. National
Museum there is also a specimen from Grandfather Mountain,
N. C., elevation above 4,000 feet, collected by J. M. Bentley,
and received through Prof. Franklin Sherman, Jr., after whom
the name shermani was proposed by Mr. Schwarz.
The species is easily distinguishable from P. carinatus Boh.
by the sculpture of the. prothorax and elytra. In P. carinatus
the prothorax is depressed above, with coarse confluent punc-
tures which are better defined on the sides. The strial punc-
tures are more prominent and the even interspaces are not
tuberculate. The occurrence of Paraplinthus in the Appalach-
ian region is rather notable, as the genus has hitherto been
32 ENTOMOLOGICAL SOCIETY
known in North America only from Alaska, and southward
on the Pacific slope through British Columbia, Washington,
and Oregon, to northern Idaho. According to Mr. Schwarz,
its occurrence is paralleled by the distribution of other genera
in Coleoptera, for instance, Necrophilus and Pinodytes of the
Silphidz. The eastern species of Paraplinthus was collected
on the underside of freshly cut spruce chips lying on the
ground. :
THE SOUTH AMERICAN COCCIDZ OF THE GENUS
ERIOCOCCUS.
By T. D. A. CoCKERELL.
It used to be supposed that Eriococcus was absent from
South America, but in recent years a few species have been
found in Brazil. Hempel cites three, but one of them, E.
armatus Hempel, is an Erium. Mr. Schrottky has sent me a
very ordinary-looking species from Villa Encarnacion, Para-
guay (his No. 2508), which upon examination proves to be
quite different from those described from Brazil. However, I
do not see that it differs materially from E. dubius Ckll., de-
scribed from specimens collected by Townsend in Mexico. The
South American species may accordingly be tabulated as
follows:
Female sac very long (11 mm.), of peculiar shape; third antennal joint
much longer than fourth; on Eugenia, etc., Brazil. .perplexrus Hempel

long; mounted 2 2-214 mm. long; antennz very rarely 6-jointed

All three have 7-jointed antenne. The antennz of the Para-
guayan insect are very like those of E. quercus Comst., and
E. tinsleyi Ckll., but the legs are not as in these species.

NOTES ON COCCIDE.
By T. D. A. CocKERELL.
Pseudococcus pandani (CKkIl.).
This species was described some ten years ago, from speci-
mens found in the Marquesas Islands, and has not been received
from elsewhere. The following measurements, from the type,
are in w, and are necessary additions to the original rather too
brief account. They are from a Q containing many embryos.
Antennal joints, (1) about 50, (2) 50, (3) 45, (4) 25, (5) 32, (6)
32, (7) 35, (8) 80. Anterior leg; coxa, 140; femur with trochanter,
270; tibia, 142; tarsus, 80. Hairs of anal ring, 125; longest hair of
lateral caudal patches, about 140. The sides have small patches of
spines.
Three distinct groups of Pseudococcus have quite similar
types of antennz; these are the groups of P. citri, of P. neo-
mexicanus, and of P. longispinus. P. pandani is a member of
the citri group, and is, perhaps,araceof citri. Itisat present an
open question what should be considered the limits of P. citri;
certainly various forms, ostensibly belonging there, present
important differences, but these may be due to individual or
racial variation. It will be necessary to measure carefully
numerous examples from each of several different localities
and food-plants, and also to find out experimentally whether
all forms can live equally well on all the plants cited for the
species.
Pseudococcus armatus (Hempel), var. a.
?.—Ovisac pure white, long-oval, closely felted, about 3 mm. long;
females greyish-black, enclosed in the ovisac and having a bunch of
short cottony tassels (much like those of P. citri) at the caudal end;
these may be seen in the opening in the posterior part of the ovisac.
Boiled in caustic potash, the females are seen to be full of a blue-green
pigment; a female full of eggs, mounted on slide, is 1650 long, 930
broad, while the eggs are long-oval, 300 long.
Skin with many round gland-orifices, not uniform in size; also some
spearhead-like spines, 12 long, set in broad sockets; and a few small
bristles. Anal ring ordinary, with six bristles. Caudal lobes quite
prominent, mammeform; labium dimerous, short, about 100 long and
87 broad at base, regularly tapering to apex; legs and antennz yellow-
ish.
Measurements in #: anterior leg; femur plus trochanter about 137,
tibia 55, tarsus (exclusive of claw) 50; claw about 20, stout, nearly 10
34 ENTOMOLOGICAL SOCIETY
broad at base, with no denticle on inner side. Hind femora plus tro-
chanter 170-175, width of femur 47. Antenne broken in the material
examined, but joint I is 45 on long side, 25 on short; joint 2 is 30;
the last joint is 62, and very bristly.
Larva. Antenne and legs very stout; antennal joints (1) 22, on the
longest side, (2) 15, (3) 12, with width 17, (4) 12, (5) 12, (6) 50.
Hind leg: femur plus trochanter 82, tibia 45, tarsus 50.
Posadas, Argentine Republic, on Baccharis genistelloides,
August 26, 1905 (Schrottky).
The ovisacs occur singly or a few together, but not bunched
in masses. Erium armatum (Hempel) is also from Baccharis,
and specimens from the type lot show that it has the same
mammeeform caudal lobes, the same spearhead-like spines, and
the measurements of the legs and antennz are not essentially
different. I found the second antennal joint to measure 25,
the last 62; the anterior leg with femur plus trochanter 142,
tibia 65, tarsus 50. Hence, in spite of some differences indi-
cated by Hempel’s description, I do not like to call the Argen-
tine insect a different species. I remove the species to Pseudo-
coccus, not because it is at all typical of that genus, but because
it is related as closely as possible to P. filamentosus (Ckll.)
and P. hymenoclee (Ckll.). Perhaps all three should be
placed in Erium, or else this generic name should be aban-
doned. The resemblance to flamentosus is remarkably close—
so close that if the insect had not been described by Hempel, I
should have hesitated to propose a new specific name for it.
The occurrence of the filamentosus type in the Argentine Re-
public is of much interest, and adds one more to the known
cases of species of the southern part of North America being
represented by those allied in southern South America.
Phenacoccus helianthi (CkIl.)
Glenwood Springs, Colorado, on a composite, apparently
Macheranthera. New to Colorado.
The original description is not as detailed as could be wished,
so I give a new one from the Colorado material, which was
collected by Mr. E. Bethel.
?.—Very pale yellowish-grey; making a long white cottony ovisac,
about 61%4 mm. long and 2 broad. Boiled, it turns red, but does not
stain the liquid. Skin with many round glands, about 5 diameter;
labium about 152 long and 112 broad, regularly tapering from base
to apex; hairs of anal ring six, about 145 long. Legs light yellowish,
bristly; tibia with six bristles on outer row.
Measurements in #: Anterior leg; femur plus trochanter, 300 (width

of femur, 90); tibia, 237 (width only 32); tarsus, 100; claw: with an
obtuse subapical denticle.
Antennal joints: (1) 50, (2) 80, (3) 67-70, (4) 45-50, (5) 50, (6)
40, (7) 37, (8) 32, (9) 60.
Larva (in @) elongate, 525 long, 225 wide. Antenne 6-jointed,
measuring (I) 25, (2) 27, (3) 25, (4) 27, (5) 27, (6) 62.
Asterolecanium delicatum (Green).
Green’s original description of this species is too brief for
recognition, and as it may be some years before the full ac-
count is given in the “ Coccidz of Ceylon,” I offer the follow-
ing notes, taken from 2 specimens received from Mr. Green:
Scale long-oval, light lemon-yellow, 1620 long, 870 broad (not
counting fringe); fringe light lemon yellow, about 300 long.
Eulecanium fletcheri (CkIl.).
Mr. E. Bethel has found this on juniper at Glenwood
Springs, Col. It is new to the Rocky Mountain region.
Kermes gillettei Ckll.
Ouray, Colorado, on oak (E. Bethel). This is the first
record from the Pacific slope. The specimens are unusually
small.
Hemichionaspis thez exercitata (Green).
This Ceylonese insect was first described as a species, and
then reduced to the synonymy of H. thee. Green has recently
restored it, at least to varietal rank, but has given it a new
name, ceylonica. Of course the original name must be main-
tained.
Leucaspis Targ., 1860.
It has been alleged that this name is preoccupied. There is
a Leucaspius, 1857, in fishes, but this may be considered to
differ sufficiently, I think.
Polyclona Menge, 1856.
This supposed genus, found in amber, must be removed ~
from the Coccide; it is probably dipterous. Ochryocoris
Menge, also from amber, is probably identical with Orthezia.
JANUARY 18, 1906.
The 2o0Ist regular meeting was held at the residence of Mr.
J. D. Patten, 2212 R street, N. W., with the President, Mr.

There has been, in recent years, a strong tendency, with
many entomologists, to divide old genera. This tendency has
been. more exploited in some orders than in others, but in
nearly all groups of insects there are now many genera en-
tirely strange to any but the specialist. Indeed, in the large
orders it is impossible for one devoting himself to an entire
order to become familiar with the ever-increasing flood of new
genera appearing in hundreds of periodicals and journals.
Almost overwhelming as it is to the specialist, is it strange
that the general entomologist, the economic entomologist, and
the collector of insects consider it an evil, second only to the
nomenclature craze?
This multiplication of genera is due to a modification of the
concept of a genus. With the early writers on entomology
the genus was a very broad group, and of variable rank ac-
cording to the author. Latreille, the father of modern ento-
mology, in his first work, the “ Précis,’’ saw the necessity of
fixing genera more definitely, and did so by elucidating their
characters. Ina few years, he, with others, assigned to genera
certain species as examples or types.
There thus arose two views as to the basis of a genus. First,
that it was an assemblage of species exhibiting certain peculiar
characters, and second, that it was a certain type-species and
forms congeneric therewith. This idea of the genotype, as an
incarnation of the genus, has gathered many adherents who
consider that any peculiarity of the type-species may be made
the distinguishing character of the genus. With them a genus
is not fixed so long as it contains two species; it may yet be
divided. They care nothing for the characters of a genus,
but rest all on the genotype. Indeed, genera are frequently
formed on a species without the mention of any distinguishing
38 ENTOMOLOGICAL SOCIETY
characters, a most ridiculous process. Some authors write
the description of a new genus and species in one, and kindly
_ suggest to the reader that “the characters of the genus may
be gleaned from the above description.” Anyone who attempts
this gleaning process will find the field full of stones and
weeds.
The other view, that a genus was definable by certain char-
acters, held sway over systematists for at least the first half
of the last century. Their idea was that when the characters
of a genus were once fully given, that genus was fixed for
all time. They commonly accepted the idea of a type as a
species exhibiting all the characters of the genus in their full
development. In fact, some of these authors cited two or
more species as types of the genus. A species differing in
some peculiarity was held none the less truly as belonging to
the genus; or with others it might be separated in a section
or subgenus. And here let me say that a subgenus is just as
logical, just as natural, as a subfamily. Of course there was
more or less deviation, but these were the predominant meth-
ods. With the increasing importance assigned to the genotype,
there come new possibilities.
SPECIES AND GENERA ALIKE UNNATURAL.
In nature species are distinguished by all manner and de-
gree of separation. One series of species may be separated only
by differences in the genitalia of the male sex. Another series
of forms may be separated not only by genitalic differences,
but by color, by secondary sexual characters, by vestiture, by
sculpture, by structural details, and by geographic range. One
series may show species after species with slight variation;
another series may display subspecies, races, aberrations, and
sports in endless variety. In one case the species seem to be
final, natural entities. By the other series one sees species in
the course of development, their limits faint or inconstant, their
characters too uncertain for language—species such as appear
distinct to the eye, yet incapable of description. I know many
have an idea that species are more definite than genera. As
well say that the leaf is more definite than the twig, or the
OF WASHINGTON. 39
twig more definite than the branch. Species, genera, families,
are all parts of one great growth—a growth that still is grow-
ing, faster here, slower there.
In fact, there is all manner and degree of isolation and rela-
tion among species, some constant, some variable. The in-
dividual is the only natural unit.
Genera are broader views of species, clusters of leaves or
twigs. Based on unnatural species they are of course unnat-
ural. In attempting to place the restless, developing mass of
insect life into the clothing of classification, sometimes the fam-
ily will fit too tightly or the genus too loosely, and species here
are not coequal to species there. As we discern these misfits
it is natural that we try to adjust them.
RESULTS OF GENOTYPE METHOD.
It is evident that the more we study a species the more points
we find wherein it differs from its allies. And by fixing our
attention upon one species as an embodiment of the genus we
narrow our ideas of the genus the more we examine the species.
In our ardor to express these newly discovered differences we
create new genera. Thus the logical outcome of such a process
is that the genera become smaller and smaller, until the genus
is equal to the species, and we could conveniently abolish
genera. By applying to the subfamily and family in turn this
gradual restrictive process we could abolish these terms also,
and in time have nothing but species.
Just as on a tree there are scarcely two twigs of exactly
the same size and shape, so there are Scarcely two insects which
are separable from all others by the same sum total of differ-
ences ; so that the term species may be also gradually restricted
until we reach the individual. Thus classification would work
its own destruction.
Resting our ideas of the genus upon one species as the in-
carnation of the genus means that we must continually modify
the generic characters, and continually narrow the limits of
the genus. No insect is as yet thoroughly known. Each new
student may read from the genotype new characters as generic.
Considering the genus as based on a type-species will result—
40 ENTOMOLOGICAL SOCIETY
is resulting to-day—in generic names destitute of significance,
-and subject to continual revision.
What do we gain by elevating each section of a genus into a
separate genus? We gain nothing but confusion. We are no
nearer a natural arrangement than before. Why must we make
a new genus every time we discover a new peculiarity of a
species? One examines the species of Papilio for days and
days; result: “ Why, ajax and sinon are not like the others at
all, they have fine characters; they are [phiclides ajax and
Iphiclides sinon.” Soon will another come along, and looking
long and carefully on ajax and sinon declare: “ Why, sinon
is not an Iphiclides; it differs in so and so, it has fine charac-
ters, it is a new genus.” Have we not seen it, and heard it
over and over again!
I am not opposed to new genera. There are plenty of them
awaiting discovery. But that is not the point. It is the
splitting up of genera previously well defined, and the eleva-
tion of each section into a genus which, in many cases, is not
as well defined as the old genus—all because the type-species
is enlarged to generic proportions.
FIXED GENERA HAVE ARTIFICIAL CHARACTERS.
It is evident, therefore, that if we desire to have a fixed
classification, its categories must rest on some definite, and
therefore artificial, basis. We cannot continually shift the
scope of our terms if we wish them to mean anything. We
must give up the idea that the genus exists in nature. We
must accept the genus as an artificial group, fitting more or less
closely to minor breaks in the chain of life. Since the genus
must be artificial, why not make it fixed and constant? Let
the genus, like the family, occupy its present position in the
scheme of classification, making sections under it as dis-
coveries demand recognition. Of course there are many
groups in which the genera have never been studied thor-
oughly, nor their characters well defined. Let us study such
groups with the idea of basing the genera on structures, and
not on species. Then they will have a permanent meaning,
and a genus that means something is useful in a thousand ways.
OF WASHINGTON. 41
If I say an insect belongs to the genus Cicindela, anyone who
has ever collected insects knows what I mean; but let the genus
be divided, and sub-divided again and again, and Cicindela
will mean nothing, except a type-species. Emphasizing the
genotype means splitting genera; emphasizing the generic
characters means better-defined genera. But what characters
are of generic value? No one man can answer with authority,
yet we may consider a few points.
CRITERIA OF SPECIES.
First, what are the structures that should define species?
The nearest we can come to the criterion of a species is its
capability of interbreeding. Therefore the structure of the
genital organs, or such secondary characters as are associated
with them, must be the best specific characters. This includes,
of course, all recognition marks or structures. No one, I
think, studying insects to-day, can long resist the conclusion
that sexual characters, although often more or less variable,
and at times but slightly developed, are the fundamental char-
acters of species. This vital difference in genitalia may find
expression in more visible signs, recognition marks, index
characters, by which the insect may know its mate. These are
of many sorts, such as punctuation, color, sculpture, etc. With
these necessary differences there may go accidental differences,
which, although not essential, may aid in the separation of
species. For example, in one fly a wing-cell may be longer than
in a closely allied species. This character cannot be essential ;
there must be accompanying it differences in genitalia or
recognition marks, or some point of vital interest to the fly.
These accidental specific characters may be of much use in
the tabulation of species, but we must not lose sight of their
intrinsically slight value.
WHAT CHARACTERS ARE OF GENERIC VALUE?
Genera should not be based on the characters used in the
separation of species, no matter how widespread or constant
they may be for groups. Although we expect that the species
of a genus shall have a certain uniformity in genitalia and
42 ENTOMOLOGICAL SOCIETY
recognition marks, differences in these points are properly of
specific value. The genus, if it is to have a meaning different
from species, must have a different basis. Neither should the
characters of species be grouped for the purpose of making
genera; the grouping of specific characters simply indicates
groups of species. It introduces no new idéa to warrant the
new name, genus. Basing the genus on the characters of
species means reducing the genus in rank, and multiplying the
genera. Never yet did an author, basing genera on the charac-
ters of species, fail to create a lot of new genera.
Again, genera should not be based, as a rule, on a single
structural point, nor on two or more related points, such as
long wings and elongate cells. Rather should we seek for two
or more disassociated characters for the foundation of a genus.
It is almost unnecessary to state that habits or coloration
should not be the distinguishing characters of a genus.
The presence or absence of a structure is of more value
than the size or development of a common character.
A character that has not been restricted to close limits within
the family is not of much use in the separation of genera in
that family.
An extreme of a variable character should not distinguish
a genus. For example, if a cell in one genus of a family is
wide open, and more or less completely closed in various other
genera, its complete closure or even stylation ought not to be
the basis of a genus.
Striking characters, noticeable at a glance, are rarely of
generic value; but minute points, especially when associated
with some habit, are of great use.
Differences in the mouth-parts, in the legs and wings, are
preeminently of generic importance. The antennz and head
furnish also good generic structures; the rest of the body is
much less valuable in these respects. We should consider the
value of a character to the insect; whether it is related to the
method of life. For example, a striking difference in shape
of the ovipositor indicates that the insect has a different method
or place of living from its allies, and we naturally expect to
find that such a form represents a genus, definable also by other
structures.
OF WASHINGTON. 43
NEED OF REVISION.
Daily in our work we come across genera which we well
know are not good genera. Why then accept them? An author
will tabulate the species of two or more genera in one synoptic
key; it being evident that the characters which distinguish the
genera are of less value, or are less constant, than the charac-
ters that separate the species. Such genera are worthless.
They mean nothing. They are of no value to science.
There is need, sore need, of generic revision in nearly all
groups of insects. If we look to the genotype as the only
source of generic characters, the work will have to be done
over again, and still again, and again. For each new student
will look closer and more sharply than the last. Let us fasten
the genus at a definite place in the scheme of classification by
giving to it constant and peculiar characters, and the name
will hold and mean something. The systematic entomologist
can do no better work than in placing genera on the sure
foundation of definite characters.
Finally, let us remember: That classification is unnatural ;
that a genus based on a type-species can be interpreted to suit
each student; that if we desire the genus to have and to carry
the same meaning at all times it must be based on definite
structures; and that dividing genera brings us no nearer to a
natural arrangement, while it is often a hindrance to our
science.
Doctor Hopkins complimented Mr. Banks on his address
and said that his experience led him to agree with the latter
that the splitting up of genera without a detailed study to de-
termine the real generic characters as distinguished from
specific characters is not contributing to advancement but
rather to the opposite. He thought that it was far better to
classify the large genera into primary and secondary divisions
and sections under one name, according to interpreted natural
affinities, rather than to introduce new names for genera and
sub-genera established on characters of indefinite separation
from established genera.
Doctor Gill stated that there is no hard and fast line which
44 ENTOMOLOGICAL SOCIETY
can be drawn in the recognition and definition of genera. The
genus is as natural an assemblage as a species, or even more
so. He believed that ultimately there will be substantial agree-
ment as to what characters are of generic value. The genera
of Linnzeus, he stated, were in many cases very unnatural.
Mr. Caudell remarked that in his studies of the Orthoptera
he had often been impressed by a fact pointed out by Mr.
Banks in his address, namely, that obvious and striking pecu-
liarities are often of no generic value. Doctor Gill said that
among birds color or pattern is more or less uniform through-
out the species of certain genera and is therefore a useful
character in such cases. He called attention to the good work
done by Leach in the erection of genera and of Kirby in
creating families, in entomology. Kirby was the first to use
the termination -idz for families in entomology.
Doctor Ashmead believed that there are genera which may
rightly be called natural. He agreed with Mr. Banks that
minute or inconspicuous characters are often more stable and
of more value in defining genera than conspicuous or striking
ones. He believed, however, that there are good generic
characters in the genitalia. The arrangement of the spiracles,
also, furnishes a good character. He thought that in very
many cases the subdivision of existing genera is not only
justifiable but desirable and necessary, and that much of the
work now being done in erecting new genera is entirely sound.
Doctor asked the question, “What is a natural group?”
The farther removed from a species a group is, the more
difficult is its definition and limitation. For instance, the
Coleoptera with the Stylopide removed form a natural group;
with them, the order is unnatural. Mr. Banks stated that there
are no good characters which serve to define all the members
of any of the larger orders of insects, nor to separate and dis-
tinguish them from members of other related orders. Doctor
Gill directed attention to the fact that parasitism obscures
natural group affinities, and that in classifying these forms
recourse should be had to embryological studies.. Doctor Hop-
kins stated that a knowledge of the life history and habits of
the species of a genus contributes greatly to a correct interpreta-
OF WASHINGTON. 45
tion of structural characters and to the classification of the
species into natural groups. Doctor Gill then spoke of the
danger there is in relying too much on similarity of habits or
mode of life as a guide to classification. With proper limita-
tions, however, ecology may furnish useful hints.
Mr. Busck thought it a rather gloomy view to take, that the
systematists should be getting away from the natural groups,
and he contended that although our present arrangement of
insects may not be perfect it is surely much nearer perfection
than it was in the days of the old authors. Doctor Dyar said
that a natural classification would be one in accord with phylo-
geny, while an unnatural one would not. _
—The following paper, read by title, has been accepted by
the publication committee :
THE CRYPTOCERATE HEMIPTERA OF AMERICA IN THE
WRITINGS OF PROFESSOR ARNOLD
L. MONTANDON.
By J. R. pE LA TorrE BUENO.
Prof. Arnold L. Montandon, of Bucarest, Rumania, has de-
voted a great deal of attention in recent years to the crypto-
cerate Hemiptera and has published a large number of notes
and papers on them, all of great value to students of the water-
bugs. American hemipterists will find these of great inter-
est, for not only has Professor Montandon published several
monographs of peculiarly American groups, but he has also
described a number of new species indigenous to the Western
Hemisphere, and corrected many synonymies, reviving for-
gotten species and establishing the distinctive characters of
many obscure forms. In addition, he has paid great attention
to the Pentatomidz, especially the Scutellerinz.
In the following bibliography are listed all the papers, so
far as can be learned, which Professor Montandon has pub-
lished to date on the American water-bugs; but papers upon
other groups of Hemiptera, or those which deal only with Old
World Cryptocerata, are omitted. It is the aim of the writer
to place in concrete form before American hemipterists the
importance to us of the work done by this European savant ;
hence the form of this list. No less important to us is an ac-
quaintance with those forms found in Spanish America and
46 ENTOMOLOGICAL SOCIETY
the Antillean islands, for many species described from the
Tropics find their way north and south to more temperate
regions—a fact which the tremendous range of certain water-
bugs has made familiar to all students.
In the bibliography (Part I) each title will be numbered,
and, to make reference easy, these numbers will be given in
the systematic list (Part IT) in parentheses after the names of
species, genera, and higher groups. In the systematic list,
also, new species will be indicated by black type, valid species
will be in Roman type, and synonyms and manuscript names
will be printed in italics. Valid genera will be in black capitals,
and synonyms in italics. The generic names in parentheses,
following any species, indicate the genus under which that par-
ticular species is mentioned by Montandon. The localities
given are only those mentioned by him, and where they are
omitted it is because he mentions none.

Doctor Howard read a letter from M. René Oberthur,
Rennes, France, who was cooperating in the efforts to introduce 2
into the United States parasites of the gipsy and brown-tail jig
moths, in which the latter stated that he had forwarded quite =
a number of brown-tail moth nests to this country; in this
connection Doctor Howard read an account, published in a
newspaper of that region, of the collecting of brown-tail moths’
nests, in which several amusing explanations were hazarded
as to the purpose of this work. Re
—Doctor Howard read also a letter from Mr. A. H. Kirk- is
land, superintendent for suppressing the gipsy and brown-tail ae
moths in the Commonwealth of Massachusetts, in which Mr.
_ Kirkland quoted Mr. F. H. Mosher as stating that he had
observed adult staphylinid beetles catching living flies. Mr.
_ Mosher’s note is as follows:
During the season of 1902 I had the opportunity to observe the feed- a
ing habits of Staphylinus maculosus Grav. Previous to this date I had ae
frequently observed these beetles in the locations where they are com-
monly found, and had supposed that they were feeding upon the material
59
60 ' ENTOMOLOGICAL SOCIETY
with which they were associated. Watching carefully, however, I
observed that the beetles crept under the edge of the material, turned
around, faced outward, and sprang upon flies as they came within
reach. The flies were then taken into grass or under leaves near by
and devoured. The beetles seemed usually to eat but two flies at a
meal. Their preference seemed to be for the common blue-bottle fly
(Calliphora erythrocephala Meig.), although a gray fly (Sarcophaga) -
was sometimes devoured. I have seen the beetles so feeding both in
eastern New York and in Massachusetts.
A general discussion then ensued, Mr. Schwarz stating that
the two groups of the Staphylinide are doubtless quite dif-
ferent from each other in their food habits; several species
will apparently eat almost anything that comes in their way,
while others seem to be strictly carrion feeders. Mr. Busck
reported seeing Staphylinide feeding on larve on leaves;
while Mr. Knab said he had seen them in the tropics resting
idly on the vegetation. Doctor Ashmead stated that while he
had never seen one of these beetles catch a living fly he knew
them to be feeders on carrion and thought that they were
predaceous also. Doctor Uhler reported observing Staphy-
linus maculosus feeding on dead animals and on the substance
of toadstools, but on nothing else. Mr. Schwarz stated that
this species is not uncommonly observed feeding on rotten fish,
but he had never seen it feeding’on vegetable matter. Doc-
tor Ashmead said he had seen this or a closely related species in
Florida feeding on one of the common toadstools after decay
had set in. Doctor Hopkins stated that members of the
family Staphylinide are often found in galleries of barkbeetles
and that some species appear to be predaceous, while others
are scavengers only.
—A query was read from Mr. G. K. Gilbert, asking about
the construction of nests of Pogonomyrmex ants in the West, -
and the reasons for the pebbles and other coarser material
placed on top. Discussion of this subject was participated in
by many of the members. Mr. Schwarz spoke on the habits of
P. occidentalis Cress. and Doctor Ashmead on the habits of P.
barbatus Sm., both describing the nests as being as of the same
general character—a large mound with a thick, more or less
solid crust above composed of coarse material, such as cinders
OF WASHINGTON. 61
(when near a railroad), pebbles, crystals, and small sticks.
Mr. Barber believed that the ants cover their nests with these
darker substances to conserve the heat. Mr. Knab thought
that the crust is always composed of material gathered from
the surface of the surrounding region. Mr. Caudell believed
that the crust is simply for protection from wind and storm.
Mr. Titus concurred in this and described his observations on
the construction of the nests of a Pogonomyrmex in Colorado
and the effect on the broken and unfinished nests of a high
sweeping wind or a severe rain storm. He did not believe
that the heat-conservation theory would hold, since in some
regions the nests are covered with white crystals. It did not
seem likely to him that an ant would place black substances
on its nest along the railroad for any such definite purpose,
while the same species, a hundred yards away, took white and
red sand and gravel. Doctor Uhler described the large nests
of Camponotus pennsylvanicus DeG. found by him near. Balti-
more several years ago, stating that these nests were some-
times 9 feet high and Io feet across.
—Mr. Pierce exhibited a large series of photomicrographs
taken by Mr. Barber, illustrating the morphology of some
of the American Strepsiptera. Inasmuch as the subjects of
these negatives are types, the negatives were denominated
phototypes. The most important features brought out were
the specific differences in the shape of the female cephalo-
thorax, and also the differences in the triunguloids, or first
larve. One print demonstrated well the fact that the female
metathorax is a part of the cephalothorax. A number of
prints showed the metathoracic spiracle of the female, andi
indicated the trachez as well. Mr. Pierce stated that up to
that time no species had been found by him to inhabit more-
than one species of host. The different species are very
readily recognizable from the females. Manuscript was:
then well in hand describing the various females and giving
illustrations, as well as monographing the existent knowledge:
of the order.
Considerable discussion followed on the manner of distri-
bution of triungulins, especially those of the remarkable meloid
beetle Hornia.
62 ENTOMOLOGICAL SOCIETY
—Mr. Caudell exhibited a colored drawing of a nymph of
Scudderia furcata Brunn. This brightly colored nymph is
not uncommon in the vicinity of Washington, D. C. A nymph
of one species of this genus, probably the same as here men-
tioned, was described by Mr. J. A. G. Rehn as Spilacris macu-
ldtus, new genus and species in the Stenopelmatine.
—Doctor Stiles propounded the query, “ Why does not an
insect grow as large as a crow or other animal?” Consider-
able discussion followed, and it was asked by Mr. Banks,
“Why does not a crow get as small as a beetle.’ Dr. Mor-
rill thought that the insect’s size was governed by the me-
chanical difficulty of construction of muscles and Doctor
Ashmead believed that its size was limited by the fact that
an exoskeleton heavy enough to contain the necessary organs
and to furnish support for the muscular attachment would
be too heavy to move.
—Mr. Weidheimer exhibited some well prepared speci-
mens of Citheronia regalis Fab., and of what he considered
to be the rarer species, C. infernalis Strecker.
—Mr. Banks presented a note on a proposed new classifi-
cation of the Limnephilidz, a family of the Trichoptera. He
stated that the spur formula, the present basis of classifica-
tion, had long been known to be defective in many cases. He
had therefore sought many times for other characters, es-
pecially in the venation and in the chetotaxy of the vertex.
Differences in these respects are useful in grouping genera,
but not of sufficient importance to serve as primary char-
acters of subdivision. Recently, however, he had found a
minute character which would divide the family into two
nearly equal groups. This character is the presence or ab-
sence of spines on the last joint of the hind tarsi. The appli-
cation of this character would divide several heteromorphous
genera, as Stenophylax and Halesus. This minute difference,
although seemingly trivial, is constant; at least more constant
than is the spur formula. Specimens illustrating this char-
acter were shown.
—Mr. Banks presented also a note on a new classification
of the ticks or Ixodoidea. The family Ixodide he divided
OF WASHINGTON. 63
into two subfamilies, Ixodinz, with Ixodes and Ceratixodes;
and Amblyomminz, with four tribes, as follows: Hzma-
physalini, for the genus Hzmaphysalis; Rhipicephalini, for
Rhipicephalus and Boophilus; Amblyommini, for Amblyomma,
Hyalomma, and Aponomma; and the Dermacentorini for
Dermacentor. _
—Doctor Stiles stated that he had been mistaken in some
tick identifications made several years ago, and having lately
had the opportunity of examining the types of several species
he could now correct these errors. He had found the stigmal
plate characters to be excellent. The species concerned are
Dermacentor reticulatus, D. occidentalis, D. andersoniu, and
D. quinquestriatus. D. occidentalis, in his early determina-
tions, is D. andersonti, and D. reticulatus is D. quinquestriatus.
—Dr. Ashmead presented a motion thanking Doctor Uhler
for his kind and bountiful entertainment and expressing the
pleasure of the Society in meeting with him in Baltimore.
The motion was carried unanimously and Doctor Uhler re-
sponded that the pleasure was all his and that he wished that
the Society could meet in Baltimore more frequently.
MARCH I, 1906.
The 203d regular meeting was held at the residence of
Lambda Chapter, ® % K, 2002 G street, N. W., the Society
being there entertained by Messrs. Couden, Hooker, and Mor-
rill. President Banks occupied the chair and the following
persons were present: Messrs. Ashmead, Banks, Barber,
Barrett, Beattie, Bishopp, Burke, Busck, Condit, Couden, Cur-
rie, Dyar, Gill, Heidemann, Hooker, Hopkins, Johnson, Knab,
Morrill, W. J. Phillips, Pierce, Quaintance, Reeves, Sanders,
-Sasscer, Schwarz, Titus, and Webb, members, and Messrs.
J. C. Mulder and J. F. Strauss, visitors.
The Society passed the following resolution:
Resolved, That members should furnish the recording sec-
retary with abstracts of all their communications to the Society
which are not in the form of written papers, and, in case this
is not done, that the reports of such communications as given
64 ENTOMOLOGICAL SOCIETY
in the minutes and corrected at a regular meeting of the So-
ciety be considered as final.
The resignations from corresponding membership of
Messrs. Clarence M. Weed and W. G. Johnson were presented
and accepted.
The corresponding secretary, in presenting his customary
report, called for donations from members of the Society
of separates of their papers, published either in the PRocEED-
INGS OF THE SOCIETY or elsewhere, the same to be incorporated
in the price list to be published of papers offered for sale for
the benefit of the Society.
M. George W. Bock, 1315 Hickory street, St. Louis, Mo.,
. and Mr. C. F. Adams, Fayetteville, Ark., were elected to cor-
responding membership.
Doctor Stiles proposed the following resolution, which was
adopted by vote of the Society:
Resolved, That the Society instruct its committee on publi-
cation to insist that every new generic name submitted for
publication be accompanied by a definite designation of a
type species, and that new generic names not so accompanied
be excluded in the future from the publications of the Society.
Mr. Burke exhibited specimens of larve, pupz, and adults
of the cedemerid beetle Calopus angustus Lec., and presented
the following notes:
NOTES ON THE LARVA OF CALOPUS ANGUSTUS LEC.
By H. E. Burke.
Calopus angustus is an insect of wide range, both geo-
graphically and according to food plant. One adult was
reared by the writer from a full-grown larva found in a
gallery in the sound heartwood of a living western cedar
(Thuja plicata). It had entered through the rotten wood of
a hollow butt. This tree was at Pialschie, State of Washing-
ton, quite close to sea level. The larva was found July 3,
1905; it changed to pupa July 15, and issued an adult female
on August I0.
On August 23 and 25 a number of small to large larve,
pup, and fragments of dead adults were found in galleries
in dead and living wood of Alpine fir (Abies lasiocarpa).
OF WASHINGTON. 65
Infested trees were quite common at the timber line on Mt.
Rainier, Washington—altitude about 9,000 feet. On August
27, one pupa changed to an adult male; September 3, two
pup changed to adult females; and on September 8 another
pupa changed to an adult male.
The insect seems to do extensive damage to living trees by
entering small injuries and working into the surrounding
living tissues, thus causing wounds that remain open, and
enlarge instead of healing over.
Adults have been taken in Texas, New Mexico, Canada
(Quebec), Nevada, California, Oregon, and Washington.*
The larva differs from all the other cedemerid larve of
which descriptions or specimens could be found in the follow-
ing grosser characters: In having no pair of ambulatorial pads
on the dorsal surface of the first thoracic segment; in having
pairs of such pads on both the 4th and 5th abdominal seg-
ments; in having well developed abdominal feet, instead of
mere ambulatorial teats; in having a pair of these feet on the
ventral surface of the 5th abdominal segment, a rudimentary
pair on the anterior ventral surface of the 9th abdominal
segment, and a pair of strong dark recurved hooks, with a
dark depression between, on the posterior surface of the 9th
abdominal segment.
The larve of the G¢demeridz illustrate very well the varia-
tion in the ambulatorial pads and abdominal legs. As nearly
as could be determined from the descriptions read and speci-
mens studied, CEdemera is the most generalized member of
the family and Calopus the most specialized.
CEdemera larvee, descriptions of which the writer has seen,
have a pair of horny plates—probably rudimentary ambula-
torial pads—on the dorsal surface of each of the dorsal seg-
ments, and no abdominal legs. Larve of Ditylus (descrip-
tions seen), Nacerdes (descriptions seen and _ specimens
examined), and Xanthochroa (descriptions seen and speci-
mens examined) have ambulatorial pads on the dorsal surface
of the ist, 2d, and 3d thoracic and Ist and 2d abdominal
segments, and abdominal legs on the ventral surface of the
3d and 4th abdominal segments. Chrysanthia (descriptions
seen) has five pairs of dorsal ambulatorial pads and three
pairs of abdominal legs, one pair being on the ventral surface
of the 2d abdominal segment. Oxacis (specimen examined),
Probosca (specimen examined), and Asclera (specimen ex-
amined) have six pairs of the ambulatorial pads, one being on
the dorsal surface of the 3d abdominal segment, and three

pairs of abdominal legs. Calopus (specimens examined) has
seven pairs of ambulatorial pads; the one on the prothorax is
missing, but there are two additional pairs, one being on the
4th and the other on the 5th abdominal segment. There are
four pairs of the abdominal legs, one pair being on the ventral
surface of the 5th abdominal segment.
—Doctor Hopkins exhibited sketches of the clypeus and
labral hooks of the larva of Calopus angustus Lec., the beetle
referred to in the previous note by Mr. Burke. From his
further studies of coleopterous larve he had, he stated, found
additional evidence to indicate that the labrum represents a
primitive segment.
—Mr. Titus read the following note for Professor Webster:
NOTE ON HADENA SEMICANA WALKER AND H. MISERA
GROTE.
By F. M. WEBSTER.
Late in June, 1903, the writer’s attention was called to in-
juries to young corn in Trumbull County, Ohio, caused by
noctuid larve, but the method of attack was quite in contrast
with that of any other larve known to him. By rearing
some of these larve, among which no differences whatever
could be detected either in appearance or method of attack,
two so-called species were obtained, viz, H. fractilinea Grote
(now considered a variety of H. semicana) and H. misera
Grote. For this reason the writer has never been able to look
upon the present arrangement of these forms as satisfactory.
From larve one-half to two-thirds grown, taken at this
time, imagoes of both forms appeared during the last days of
July and up to August 10. Their method of attacking the
corn was quite unique, in that they crawled up the plants and
eating downward devoured the whole stem to near the roots.
If the plant happened to be a small one, 2 or 3 inches high,
the larva entered the folded younger leaf, but if the plant was
larger it ate along the edges of the central leaves until it
reached the more tender portion and then worked directly
downward. At that time the writer was unable to find any
published statements relative to the habits of these insects, nor
has anything of that nature since appeared.
On June 13, 1905, after the lapse of twelve years, reports
of injuries of a precisely similar nature, accompanied by larvee
OF WASHINGTON. 67
clearly like those observed in Ohio, were received from Mercer
County, Pennsylvania, which adjoins Trumbull County, Ohio.
The farmer sending the larve described their work, and stated
that they had appeared in his section for the first time. Of
course this last statement is incorrect, but it might be safely
said that they had not been seriously abundant before.
While both of these so-termed species are widely distributed,
it is interesting to note with what rarity they occur in destruc-
tive numbers, even in approximately the same locality.
The question of the identity of these two forms must, of
course, still remain obscure until further rearings can be made.
That two species, differing only or even mainly in color, whose
larve are not distinguishable in appearance or method of
attack, should inhabit the same locality and food plant would
constitute an interesting biological problem.
Of the writer’s Ohio specimens, H. fractilinea was first
determined for him by Prof. G. H. French; and H. misera by
Prof. John B. Smith, who stated that he had in his collection
a specimen of this latter form taken in Colorado by Bruce, and
another one bred by Dr. Otto Lugger; also several specimens
of H. fractilinea from Doctor Lugger, which he thought were
reared also.
A rather poorly illustrated note on these forms will be found
in Bulletin 51, Ohio Agricultural Experiment Station, pages
139-141, figures 22 and 23, 1893.
—Doctor Stiles presented the following note:
THE TYPE SPECIES OF CIMEX LINNAUS, 1758.
By Cu. WARDELL STILEs.
The writer has been requested to examine the question of
the type species of the genus Cimex Linnzus, 1758, and to
place his opinion in regard to the same on record. After an
examination of the literature covering the case, he is of the
opinion that lectularius, the common bedbug, is the type of
Cimex. This decision is based upon the Linnean rule. Lin-
nzus in 1751 gave the following -rule to govern the division
of his genera:
“Si genus receptum, secundum jus nature et artis, in plura dirimi
debet, tum nomen antea commune manebit vulgatissime et officinali
plante.”
It seems to be beyond question that lectularius was the most
common of the species of Cimex mentioned by Linnzus, and
68 ENTOMOLOGICAL SOCIETY
in a certain sense it is also an officinal species. Since Linnzeus
clearly stated the principles that govern the division of his
genera, he should be taken at his word and the type should be
fixed accordingly. To take Linnzus at his word results in
selecting Jectularius as the type of Cimex.
To the objection against this ruling raised by some authors,
namely, that Linnzus defined Cimex as possessing four wings
while Jectularius was given without wings, it may be replied
that in naming a genus we name the object, not our concep-
tion of the object. Hence the generic diagnosis given by Lin-
nzus should not be held to be of greater importance than the
distinct statement by Linnzus that in case of a division of his
genera, the old generic name should follow the most common
species.
—Mr. Phillips exhibited a puparium resembling that of the
Hessian fly (Mayetiola destructor Say) taken the summer
before on a native grass (Agropyron), at Richmond, Ind.
He was unable to say whether or not it really was that of the
Hessian fly. Larve of the latter are thought to survive only
on wheat, barley, and rye, and the “ flaxseeds” sometimes
found on various native grasses have been supposedly the
pupze of some other species more or less closely related to the
Hessian fly.
—Mr. Heidemann exhibited three new species of the hemip-
terous genus Aradus and presented the following paper:
THREE NEW SPECIES OF NORTH AMERICAN ARADIDZ.
By O. HEIDEMANN.
Aradus shermani, n. sp.
Body narrow, very elongate ovate, uniformly deep black, and finely
granulate. Head much longer than broad; apical process straight, ex-
tending beyond base of second antennal joint, rounded at tip, compressed
on the sides; antenniferous processes sharply pointed, slightly diverging,
and not quite reaching to tip of basal joint of antennz; on the disk of
head between the eyes is a U-shaped deep impression; the postocular
part of head tumidly rounded. Antenne smooth, as long as head and
pronotum together; basal joint very short, cylindrical; the second a
trifle longer than twice the length of the third, both gradually thick-
ening towards the apex; apical joint somewhat shorter than the
penultimate, fusiform, pale at tip. Rostrum slender, reaching to the

broad as long, widest at the middle; lateral margins not rounded ante-
riorly, somewhat reflexed and sharply toothed; posterior margin widely
sinuate and forming broadly rounded flaps behind the humeri; on disk
of pronotum are six longitudinal lines, the last ones much abbreviated ;
in the female the median lines approach each other in the middle, while
the male has these longitudinal lines parallel. The shield-like scutellum
longer than pronotum, with two sunken points at base, and tumidly
elevated before the middle. Hemelytra much narrowed towards the
tip, reaching the base of the sixth abdominal segment; the male has
the hemelytra broader and longer; the corium is at its base only feebly
dilated exteriorly, a little upturned, the dilation not extending laterally
farther than the pronotum; membrane with the veins dull black, ex-
cept at base, where there is a small oblong whitish spot. Abdomen
long and narrow in the female, shorter in the male; edge of abdomen
finely crenulate.
Length, 2 7.4 mm., ¢ 6.8 mm.; width across abdomen, 2? 3.4 mm, d
3 mm.
Three females and one male, Southern Pines, N. C., June,
1904 (Sherman) ; Greensburg, Pa. ( Wirtner).
Type.—No. 9866, U. S. National Museum.
This species might, at first sight, be easily confused with a
dark specimen of Aradus acutus Say. But on closer examina-
tion a considerable diversity becomes evident. Say’s species is
larger and broader and has the antenne stouter and longer. I
shave named the species in honor of Prof. Franklin Sherman,
Jr., who has extensively collected the Aradide of North
Carolina.
Aradus coarctatus, n. sp.
Body compact, short, nearly subquadrate, the broadest part behind
middle of abdomen. Color dark brown, with some paler spots. Head
a little longer than broad; apical process much compressed on the-sides;
rounded in front, somewhat tapering towards tip and reaching nearly
to one-third the length of the second antennal joint. Lateral spines of
head broad at base, a little diverging exteriorly, extending to apex of
basal joint of antennz, and having at about the middle of sides a minute
tooth; there is also quite a prominent tubercle in front of the eyes and
another obtuse one on the postocular part. Antenne very long and
thick in comparison with the size of the insect; basal joint of antenne
short, only half as broad as the two following ones; the second joint
abruptly pointed towards the base, in length equal to the two last
joints; the third somewhat longer than the fourth; joints 2 and 3
strongly covered with close, thick, and erect squamules; terminal joint
less stout and more smooth, finely hairy and whitish at tip. Rostrum

extending slightly over the front coxe. Pronotum sublunate, a iittle
more than twice as broad as long, and shorter than the head; the sur-
face rather flat, remotely granulate, more densely on the posterior part
of pronotum; anterior margin straight, the posterior one feebly sinuate;
lateral margins anteriorly somewhat rounded, broadly reflexed and
irregularly toothed, the teeth becoming finer towards the humeri; the
rounded humeral flaps not prominent, with the inside margin narrowly
pale; the longitudinal ridges on disk of pronotum roughly granulate,
the two middle ones nearer together than the others, touching the
anterior margin, the others interrupted. The scutéellum seems rather
small, and, as in all three specimens before me the pins are unfor-
tunately thrust through the scutellum, a definite description of that
part can not be given. Hemelytra pale, the edges, veins, and cross-
veins strongly granulate, dark brown; the corium on the outer margin
nearly straight, extending to base of fourth abdominal segment of the
connexivum, at apex pointed; the exterior rounded expansion at base
ef corium not prominent, the edge a little upturned and finely denticu-
late; membrane brownish and the veins and spaces around them
whitish, Wings iridescent. Abdomen reddish brown, with some paler
marking, densely and finely granulate and minutely pubescent; abdomen
at middle deeply furrowed longitudinally. Genital segment of male
abruptly deflexed posteriorly, the genital lobes a little upturned, broadly
rounded and incised at the inner sides. Feet yellowish white, with
brown bands at middle of femora and tibiz, and at the knees; apex of
tibiz and tarsi clouded with brown.
Length, 3, 4.4 mm.; width across abdomen, 2.2 mm,
Three males, California (Coquillett).
Type.—No. 9867, U. S. National Museum.
This species is easily distinguished from other allied forms
by the comparatively stouter antenne and larger head. It
resembles A. ornatus Say in the form of the antennal joints
and somewhat also in robustness of body, but differs in being
considerably smaller and very differently colored, and it has
the widest part of pronotum behind the middle, contrary to
Say’s species, which has its pronotum wider towards the front.
Aradus compressus, n. sp.
Body large and thin, broad, ovate; color dull black. Head longer
than broad, finely granulate, the granules at the disk in longitudinal
rows; the sides inside next the eyes a little excavate, with a deep
sunken point before; anterior process of head very long, narrow,
rounded off at tip and reaching beyond base of second antennal joint;
the antenniferous spines long and very acute, the outer side straight.
Antenne in length about equal to the broadest part of pronotum; first
joint shortest, cylindrical, as stout as the apical joint; the second

twice as long as the third, gradually thickening towards the apex;
third joint equally thick; last joint fusiform, pale at tip; all the joints
minutely granulate and a few scattered granules of a whitish color
appear. Pronotum twice as broad as long; lateral margins strongly
and broadly reflexed near the middle, anteriorly deeply sinuate, pos-
teriorly rounded, then nearly rectangular next to the humeri, with a
narrow yellowish edge; humeral flaps somewhat depressed; edge of
lateral margins minutely dentate; anterior margin straight, narrowly
carinate;. posterior margin almost truncate; the frontal disk carries
longitudinal prominently raised lines, the inner two approaching each
other at the anterior margin, the others interrupted by the callosities,
which are defined only feebly; the surface of pronotum is finely granu-
late, especially on the posterior part, in transverse rows. Scutellum
cordate, having the margin strongly raised and the surface before
the middle slightly tumid. Hemelytra long, with the membrane dull
black and broadly rounded at the end; corium a little sinuate on
the outer sides and the basal part only feebly dilated and reflexed, the
apex reaching beyond the base of the fourth abdominal segment at the
connexivum. Abdomen gradually rounded towards back of the middle,
where it is widest; the upper side of abdomen blackish-brown, the
posterior segmental margins somewhat elevated on the connexivum, and
externally at their angles near the incisures is a small ochraceous spot;
the inner margin of the female genital lobes is also’ edged with
ochraceous; underside of abdomen at the venter flat, near the sides
much compressed and marked with reddish brown; venter narrowly
keeled throughout the middle. Posterior margin of the fifth ventral
segment trisinuate;- the sixth feebly incised at the middle, longer than
the first genital segment, which is nearly thrice the length of the
second; the genital lobes, seen from below, .rather long, converging,
but considerably apart from each other; the outer margins straight, a
little knobbed in the middle, the inner margins rounded and meeting
the outer angle of the second genital segment.
Length, 8 mm.; width across abdomen, 3 mm.
Two females, Washington State (Ulke); Seattle, Wash.
(Uhler).
Type.—No. 9868, U. S. National Museum.
This species has a great resemblance to Aradus ampliatus
Uhl., but differs from it essentially in the shape of the female
genital lobes, which are much shorter in A. ampliatus, truncate
at apex, and only slightly incised in the middle; furthermore,
the latter has a more robust body and the pronotal sides are not
sinuate anteriorly. Prof. P. R. Uhler has kindly presented
me with a specimen from his collection that bears the manu-
script siame of A. compressus. In describing the species I
gladly adopt this name. | |

Mr. Schwarz asked Mr. Heidemann how much is known
of the eggs of Aradidz. Mr. Heidemann replied that little is
known concerning the eggs. He himself had found eggs of
- only one species, namely, Neuroctenus simplex Uhler. These
were under the bark of oak and resembled the eggs of the bed-
bug. Mr. Sanders stated that he had found eggs of Aradus
cinnamomeus Panz. under loose bark of Pius inops. They
were placed in a cottony nidus resembling that of Pulvinaria.
Doctor Ashmead stated that he had never found Aradidze
under living bark, but he had found them under the bark of
orange trees killed by frost, in Florida. Mr. Heidemann stated
that on two occasions he had found Aradus breviatus Bergroth
under the living bark scales of pine trees near Washington,
D. C. Mr. Burke gave it as his belief that one of the western
species, Aneurus simplex Uhler, occurs under scales of bark
of living spruce trees.
—The following paper, by Dr. G. W. Harvey, of Adin, Cal.,
was then read by the recording secretary:
A FEROCIOUS WATER-BUG.
(Pedinocoris macronyx Mayr.)
By G. W. Harvey, M. D.
In the warmer streams and ponds of California lives a crea-
ture whose character is aptly portrayed by the word ferocious.
He might be termed a giant for his fierceness and strength
were it not for the fact that the so-called electric light bug is
a neighbor of his and about twice his stature. Among the
children who go wading in the streams this bug is known as
“toe pincher,” because he frequently mistakes their toes for
lawful quarry and thrusts savagely into them with his scimitar-
like proboscis. They tell me that his bite is very painful,
though not at all dangerous.
Scientifically this bug bears the title of Pedinocoris ma-
cronyx. It is of a uniform dull brown color, with a barely
perceptible mottling on the elytra. The females are possibly
a shade darker than the males. It has protruding beady black
eyes, and its head terminates in a long curved proboscis about
7 millimeters in length, which gives it a very odd and savage
appearance. Its legs are hairy, and armed with sharp curved
claws, very long and prominent on the two front legs, which
OF WASHINGTON. 73
are placed well forward and work in a vertical plane. These
legs are jointed at a very acute angle in the second joint, and
the claws on them can be bent down upon the first joint of the
leg, thereby clamping the prey as in a vice. It is with these
powerful and formidable front legs that it captures its prey.
In size it is 3% centimeters long, with a reach of 1% centi-
meters more to its front legs and a breadth of 2 centimeters
across the back.
Nature has gifted this bug with a voracious appetite. Its
aggressive prowess as a hunter is something appalling to the
owner of an aquarium who chances to secure a specimen, and
I well remember my first experience with it. My aquarium
contained a beautiful collection of aquatic insects, fish, snails,
tadpoles, etc., from the streams about Watsonville, Cal., and
it was on a collecting ramble that I discovered Pedinocoris.
To me it seemed a wonderful insect and I took it home highly
elated over the prospect of a new creature to study. That
night I placed it in the aquarium and I was around early the
next morning to see how it had fared in its new quarters.
Imagine my astonishment to find it sitting complacently on a
stalk of Sagittaria devouring a beautiful trout, almost, if not
quite, 3 inches long, while all about were scattered the exsuf-
flicated skins of many victims—young frogs, tadpoles, fish,
snails, and various smaller fry. He had fared altogether too
well—much like a weasel in a hen-house. At that rate my
aquarium would soon be totally depopulated, so I removed the
bug to less commodious and more sparsely populated quarters,
and confined it to a diet of tadpoles and young frogs. Of these
it would devour dozens in the course of twenty-four hours.
The prey were captured, as they swam near, by a sudden dart
forward. The hooked front legs were suddenly thrown over
the victim, and the sharp proboscis was thrust into the quiver-
ing flesh, not to be withdrawn until the skin was a limp and
flabby sack of lifeless refuse.
The habit of Pedinocoris was to lurk in the most secluded
and darkened places, backing up occasionally to the surface
for a breath of fresh air, and quite often, after returning to
the lurking place, raising and lowering the wing-sheaths as
though breathing, for beneath these could be seen a large
bubble of air, advancing and receding with the up and down
motion of the wings. When I took it from the water it would
play possum for five or even seven minutes, but when aroused
it was full of life, and if held firmly for a moment or two it
would eject a few drops of clear liquid, even to a distance of
3 or 4 feet.
Occasionally, it would come stealing to the surface where
74 ENTOMOLOGICAL SOCIETY
a thick mass of duckweed was floating, extrude the spiracles,
and make a soft chirping noise, not unlike a subdued cricket
song. It was some time before I could make out just where
the music came from, but I finally succeeded in observing the
act, and verified it a number of times. That a song could
emanate from so odd a source as the rectal spiracles of a water
bug seemed unnatural, but such is the fact. When the bug
was engaged in chirping one had to look very closely among
the duckweed to discover the spiracles, but, once found, a
rhythmical contraction and relaxation could be distinctly ob-
served with every note of the song, which was produced much
more slowly than that of our cricket.
The breeding season of this water bug at Watsonville, Cal.,
where it is very abundant, is from April to June, and during
this time from two to four sets of eggs are hatched. The eggs
are glued tight and fast to the back of the male, and there they
stay through the whole period of incubation. Upon the wing
sheath of the male is first spread a drop of mucilaginous adhe-
sive. Into this drop of adhesive are fastened the eggs, one at
a time, closely together, at all angles from perpendicular in the
center of the clutch to a cant of 45° at the edges of the wing
sheaths. From 70 to 175 eggs are deposited upon the back
of the male, but not all at one time. Part of them will be
deposited one night and the rest the next or succeeding nights.
This work is all done in the dark and I was never fortunate
enough to observe it. If a spot of two, three, or more eggs
is missed, it is filled in afterwards, and should some of the
eggs prove to be infertile, these drop off and are replaced by
others as late as the sixth or eighth day of incubation.
Incubation lasts from ten to twelve days, at the end of which
time the egg cases and adhesive nidus that holds them are cast
off entire, providing there be no late-laid eggs, in which in-
stance the empty egg cases and nidus remain attached until
all are hatched. The cast-off mass of egg cases and nidus
resembles a knobbed shield, being oblong-oval, with the con-
cave side towards the male’s back. The eggs are 5 millimeters
long by 1 millimeter thick and are of the same color as the
parent. During the period of incubation the male spends much
of his time in aérating the eggs. This is accomplished by
gently raising and lowering the wings so that the air taken in
at the surface and held under the wing cases is moved back and
forth beneath the mass of eggs, and taken up a little at a time.
If by any chance the male should be removed from the water
for a few hours during incubation, the whole mass of eggs—
nidus and all—loosens and comes off.
At the end of incubation the male comes to the surface and
OF WASHINGTON. 75
with his back partly out of the water the young begin to appear.
The first thing seen after the rupture of the egg case is a pair
of beady black eyes. At the first appearance of the young the
male begins raising and lowering the wings, at the same time
going through a jerking manceuver at regular intervals. The
young insect is extruded from the egg by easy stages, the
hatching being accomplished in from seven to twenty-five
minutes. At birth the young bug is about 5 millimeters long
by 2 millimeters broad, of the purest white, rapidly changing
to a light straw-yellow and brown. In two or three hours at
most it is of the same color as the parent and, if prey be not
abundant, very likely feasting on its fellows. This latter trait
is evidently hereditary, since the parent often makes a meal of
its own offspring.
These bugs disdain nothing for food that they can handle,
dead or alive. They often come to the surface for floating
insects, worms, moths, butterflies, dragonflies, grasshoppers,
crickets, caterpillars, etc., and after extracting all the nourish-
ing properties cast the skins aside. Their migrations are made
at night.
_ Mr. Burke stated that the range of this species extends up
into the eastern part of the State of Washington, and that there
its common name is “ toe-biter,’’ not “ toe-pincher.”’

The 204th regular meeting was held at the residence of Dr.
Wm. H. Ashmead, 1807 Belmont avenue, N. W. President
Banks occupied the chair and the following members were
present: Messrs. Ashmead, Banks, Caudell, Currie, Hopkins,
Knab, Quaintance and Titus.
By vote of the Society the Executive Committee was in-
structed to take action relative to the storing of the publications
of the Society in some fire-proof storage building.
Doctor Hopkins exhibited a drawing of the reproductive
organs of females of the genus Pissodes and explained the use
and mechanism of the spermatheca in these beetles.
—Doctor Hopkins showed also some hibernation cells of
larve of the locust borer (Cyllene robinie Forst.), a cerambycid
beetle. These are formed just beneath the outer corky bark
and in the outer portion of the living inner bark of the black
76 ENTOMOLOGICAL SOCIETY
locust (Robinia pseudacacia). The wound thus produced
results in a small dead area surrounding the cell, which was
found to extend through the thick inner bark to the wood
itself. The hibernating larve are very small. Normally but
one egg is deposited by the beetle in a place, instead of clusters
of from 4 to 9g as stated by Gen. H. A. S. Dearborn, who was
the first to record the more important facts in the life history
and habits of this insect. The beetle selects healthy spots for
oviposition, thus making the injury more extensive than it
would otherwise be. The dead portion of the plant tissue
around the larval cells resembles somewhat the bark killed by
the pear blight and seems to be of a similar nature.
—Mr. Caudell reported that assistants of Mr. A. H. Kirk-
land, Superintendent for Suppressing the Gipsy and Brown-
tail Moths, had lately taken from 25 to 30 cocoons of a Japa-
nese limacodid moth (Cnidocampa flavescens Walk.) near Cape
Cod, having mistaken them for those of the gipsy moth. This
species was introduced into North America many years ago,
but has not been taken before in the Cape Cod region, so far
as known. In this connection Mr. Caudell stated that Doctor
Dyar had experienced considerable difficulty in inducing bred
limacodid moths to mate in captivity. Mr. Knab stated that,
as regards chrysomelid beetles, most of those that emerge in
the fall do not mate until the following spring, and he thought
that some similar explanation might account for this failure
to mate in the case of the limacodids. Professor Quaintance
stated that he had a record for the plum curculio in which
specimens mated in summer almost immediately after emerg-
ence from the pupa, and larve therefrom were reared almost
to maturity. Doctor Hopkins stated that in Europe bark wee-
vils of the genus Pissodes do not mate until a year after they
emerge and are known to live three years and to oviposit each
year. Mr. Knab stated that he had reared the larva of the
cerambycid beetle Orthosoma brunneum Forst. to the pupa in
an old railroad tie. Doctor Hopkins stated that larve of the
locust borer (Cyllene robinie Forst.) develop, transform, and
emerge from a gallery little more than twice the length of the
full-grown larva. Larve under dry conditions completed their

development and emerged thirty days earlier than those under
moist conditions. Professor Quaintance said that the same
thing .holds true for the peach borer (Sanninoidea exitiosa
Say), the larve from nearly dead trees transforming before
those from trees which are living and more or less vigorous.
He then described the method of birth and the prolificacy of
the black peach aphis (Aphis persice-miger Er. Sm.) no males
or eggs of which, as is also the case with the cabbage aphis
(Aphis brassice L.) and the cotton or melon aphis (Aphis
gossypii Glov.), have ever been found. Mr. Titus stated that
some specimens of the melon aphis had been known to repro-
duce agamically for two years. During all this time they were
under observation and it was known that no eggs were laid.
—Mr. Banks made some remarks on the classification of the
Perlidz and on the characters which he had found to be most
valuable in the separation of the various groups. Doctor Hop-
kins asked him whether there were good sexual characters in
the Perlidze, and Mr. Banks replied that there are characters
‘ in the anal plate. Doctor Ashmead said that there are charac-
ters in the anal veins of saw-flies, but that these disappear in
the higher Hymenoptera.
—Mr. Knab made some remarks on the habits of South
American passalid beetles. Among other thing's he stated that
they seem to be monogamous. ‘The larve are cared for by the
adults, and this care is evidently necessary to the larve.
—Doctor Ashmead reported the taking of a ponerid ant,
Leptogenys falcigera Rog., in the Philippines. It had pre-
viously been recorded from Ceylon and Madagascar.

A REVISION OF THE NEARCTIC CONIOPTERYGIDE.
By NATHAN BANKS.
(Piates VI, VII.)
The Coniopterygidz are a small and peculiar family of the
true Neuroptera. One of the most characteristic marks of
the family is the mealy exudation upon the wings and some
parts of the body. More vital structures, however, distinguish
the group from its allies. The antennz are short, moniliform,
78 : 3 ENTOMOLOGICAL SOCIETY
and hairy; the wings have very few transverse veins, rarely as
many as 10, and no series of costal cross-veins such as is found
in all other true Neuroptera, nor are the veins forked just
before the margin as in nearly all allied forms. The maxillary
palpi have five joints, the last joint longer and more slender
than the others; the labial palpi have three joints, the last joint
large and compressed. There are no ocelii. The hind wings
are smaller than the front pair, without anal space, and the
margin is very minutely ciliate. The legs are moderately long ;
the middle and hind tibize are often fusiform; the tarsi are of
five joints, the basal joint the longest; the claws. are simple.
The abdomen is shorter in the male than in the female; the
genitalia are not very distinct; but I have figured their shape
in the males of two species.
The adults can be collected from various trees and shrubs in
late spring and summer by beating.
I have found the larva of Coniopteryx several times on the
leaves of various trees at and near Washington, D. C. It is
a rather flat, fusiform larva, broadest on the mesothorax, hav-
ing a triangular head, with the middle portion slightly extended,
and antenne that are two-jointed and cylindrical. The color
is dark reddish or brown, with bands and spots of white. The
tip of the abdomen ends in a slender sucker. In California
Professor Woodworth has observed the larva of a Coniopteryx
—a mottled black and white larva—sucking the eggs of the
red spider. He noticed that when fully grown it spun a double
cocoon, made up of an outer flat layer and an inner spherical
case.
In Europe the larve of two genera, Coniopteryx and Aleur-
opteryx, have been described by Low. The former has a very
slender beak and slender palpi; the antennz are also simple,
of two joints, the second much the longer and tapering to the
tip. In Aleuropteryx the beak is short and broad at base; the
palpi have the terminal joint greatly swollen; the last joint
of the antennz is truncate at tip and rather broader there than
elsewhere, and has a long bristle; the body is more slender
than in Coniopteryx.
The Aleuropteryx larva was found feeding on scale insects
on a pine tree. It pupated in a double cocoon, composed of
an inner dense spherical case and some loose outer layers. It
remained in the pupal state twenty days. Dr. Low, who bred
this larva, believed that there were two generations in a year.
I think that our eastern species have two generations each year,
as Mr. J. H. Emerton has recently bred Coniopteryx vicina
from cocoons found during the winter.
These tiny mealy-winged insects were a puzzle to the early
OF WASHINGTON. 79
entomologists, yet the first species described—by Miller in
1767—was placed correctly in Hemerobius, as that genus was
then understood. Other authors, however, placed them in-the
caddice-flies, in the Psocidz, and in the Aleyrodide. West-
wood was the first to show their true position, and Burmeister
the first to consider them a distinct family.
Very little work has, until recently, been done on the Coniop-
terygide, either in this country or in Europe. In 1885 Dr.
Franz Low published a revision of the then known European
forms, and-recently Dr. G. Enderlein of Berlin has given us
several papers, including an elaborate classification and a mono-
graph. On one important point, however, I differ from that
author as to the type of the genus Coniopteryx. Curtis* gives
C. tineiformis as the type of his genus Coniopteryx, and gives
figures of the venation. In his generic description he says
that there are three closed cells in both wings; and the figures
show that in the hind wing the median vein is forked as well
as the radial sector, and that in the fore wings the connecting
veinlet from the cubitus runs into the lower branch of the
median vein, instead of directly into the median vein; in other
words, the venation is on the same plan as Low figures for
C. aleyrodiformis. Low considers that Curtis had two species
in his C. tinetformis, for Curtis says, “antenne about 25
joints,’ and the size given is too small for C. aleyrodiformis.
He admits that the form Curtis figures is C. aleyrodiformis,
while the form fitting to the size and antennz, he says, is
C. lactea Wesm. Curtis may not have been careful in counting
the antennal joints, for it is not easy to be sure of their number,
and the size as given by him may have been.a misprint. But
even if Curtis did have two species before him, surely the
name must hold for that form which he figures, and to which
figures he refers in both the specific and generic descriptions.
This reference in the specific description to the figures makes
the venation exhibited by the figures an integral part of the
description, a part fully as important as the number of antennal
joints or the size. Moreover, Tullgren, in a recent paper on
the Swedish species, claims that the male of lactea Wesm., has
28 joints in the antennz instead of 25, so that the differences
in this respect between the two forms is less than was sup-
posed by previous writers. There cannot be the faintest doubt
as to what the figures of Curtis represent, and since he consid-
ered them typical of both genus and species, they must stand
for C. tineiformis, rather than the doubtful supposition that
Curtis had C. lactea before him, a form totally at variance
with the figures.

Enderlein* has made a new genus, Semidalis, for C. aleyrodi-
formis, but,,as I have shown, Curtis’s own figures show that
C. tineiformis has the same venation as C. aleyrodiformis;
therefore Semidalis is a synonym of Coniopteryx. Wesmael
described his species as Malacomyza lactea, and the genus is a
good one. Fitch based his genus Aleuronia on a precisely
similar form; therefore it is a synonym of Malacomyza.

Abdomen nearly black. Legs. brown, mealy; the hind tibia plainly
fusiform, one and one third times as long as femur; tarsi short. Wings
‘dark, mealy (when not rubbed), the extreme outer margin of fore
pair often pale. Venation as figured, the veinlet connecting subcosta
and radius about its length or more beyond the veinlet closing discal
cell; no cross-vein between first and second anal veins. In hind wings
the venation is very similar to that of fore pair; the hind wings in
both sexes reaching beyond discal cell of fore wing. The apical and
posterior margins in both pairs are minutely ciliate. The abdomen of
male is very short, and ends as in figure; in female it is nearly twice
as long and swollen in the middle.
Length, 2.642.9 mm.
I have specimens from Sea Cliff and Hamburg, N. Y.;
Lakehurst, N. J.; Plummers Island, Maryland, and Falls

of Comparative Zoology; it has outer margin of forewings
pale; it is from Washington, D. C. This is our most common
species.
Coniopteryx angustus, n. sp. (Pl. VII, fig. 8).
Very similar to C. vicina, but the fore wings are more elongate and
slender, the apical margin not pale. Venation like C. vicina, except
that the veinlet connecting subcosta and radius is fully three times its
length beyond that closing the discal cell; and that the forks of the
radial sector are longer. In the male the upper genital appendage
tapers toward tip, while in C. vicina it is rather clavate.

Type: A. low Klapalek.
This genus was supposed by the Cathe to be based on
A. lutea Wallengren, but it has been shown that. Low’s species
was not the same. Enderlein has recently? made a new genus
-—Helicoconis—for A. lutea, but the differences, in my opinion,
are altogether. too slight to be of generic importance ; the exotic
species he places in this genus probably represent two new
genera.

Head yellowish; antennz yellowish, short, of about 24 joints; thorax
brownish; abdomen yellowish brown; legs brownish, hind tibia not
swollen, tarsi long and slender. Wings pale, somewhat mealy (speci-
men partly rubbed), margins with long cilia, those on costal margin
shorter than elsewhere. Wings with venation as figured, the cross-
- veins in groups, the cross-vein from subcosta to radius only a little
beyond that closing discal cell; four basal cross-veins present; in the
hind wings the radial sector arises'near the base of wing and is
forked before the oblique cross-vein closing the discal cell; the median

scales on second joint and in the tuft; terminal joint dark. Head and’
thorax dark brown. Basal half of fore wings ochreous brown, very
sparsely sprinkled with white scales; in this brown part is a narrow
oblique fascia of bluish metallic scales from basal third of costa to the
middle of the dorsal edge; this fascia is joined in the middle of the
wing by another bluish metallic streak from the middle of costa and
together they form a perfect though not very distinct Y. Just beyond
the middle of the wing the basal unspeckled part is rather sharply
terminated and the rest of the wing is profusely speckled with ochreous

wing to termen; on the middle of the fold is a short longitudinal black
streak, above this in the cell is a larger longitudinal streak, and at
the end of the cell is a third very short black streak or dot. A few
single black scales are sprinkled over the apical half of the wing along
costal. and- dorsal..edge. Cilia pure. white, with base, tip, and two
transverse lines black. Hind wing light ochreous fuscous. Abdomen
ochreous. Anterior legs white, with a longitudinal black line through
their entire length; posterior legs pure white, tarsi shaded with ochreous
and with each joint tipped with black.
Alar expanse, 15 mm.
Bright Angel, Ariz. (H. S. Barber).
Type—No. 9891, U. S. National Museum.
The species is closest to Paltodora magnella Busck, but
smaller, brighter ochreous in color, and without the costo-
apical white dashes. The peculiar ornamentation of the fore
legs makes easy the distinction of this species from all de-
scribed American species of the genus except dietriella Busck,
which has a similar ornamentation not mentioned in the descrip-
tion. The wing color and markings, however, separate it from
this rather dark ochreous species.
Sophronia primella, n. sp.
Antenne shining dark brown, without color annulations. Labial
palpi whitish, mottled with ochreous fuscous, especially on the exterior
side and in the large well-developed brush. Face whitish. Head and
thorax whitish ochreous, strongly mottled with dark ochreous and
fuscous scales. Fore wings ochreous, mottled and longitudinally
streaked with white, black, and fuscous. Costal edge from base to
apical third white, edged below by a narrow streak strongly mottled
with fuscous. Below it is a nearly unmottled area of clear ochreous,
reaching to the middle of the wing and only transversed by a single
dark line on the subcostal vein. From base through the center of the
wing run close beside each other two parallel black lines, interrupted
at the end of the cell by a round brown dot, but continued on the
other side nearly to a small round black dot at apex. The dorsal part
of the wing is rather freely dusted with white and brown scales and
on the middle of the fold is an oblong brown dot. Cilia long, white,
with two dark lines parallel with the edge of the wing and with a long
thin deep black pencil at apex, which is slightly falcate. Hind wings
light ochreous fuscous; cilia light ochreous. Abdomen dark fuscous.
Legs ochreous, tarsi annulated with black.

This is the first record in America of this interesting Euro-
pean genus. I have been unable to examine the type of the
genus Illustrella Hubner, but presume that the other species
placed with it in this genus by Rebel are truly congeneric, and
the present American species has the same general habitus and
the identical oral and venational characters as these. The
venation is as follows: Fore wings, 12 veins, 7 and 8 stalked
to costa, rest separate; hind wings, 8 veins, 3 and 4 closely
approximate or connate (in primera approximate), 5 nearest
4, 6 and 7 stalked.
I have long had the type of this species, but have been in
doubt about its locality label, which reads: “From Boll,
Texas.” Such labels were placed, during a short period, on
Microlepidoptera from any locality by a young inexperienced
worker in the Department of Agriculture and are consequently
not dependable. Some European specimens, for example,
bear such a label. I have, however, examined and deter-
mined specimens from Cochise County, Ariz., and from Den-
ver, Colo., for my friend, Doctor W. G. Dietz, and have thus
at least two good localities for the species.
I have met with another species of this genus, collected in
New Jersey, but have not sufficient material to properly de-
scribe it at present.
Telphusa velatella, n. sp.
Antenne silvery white, with black annulations. Second joint of labial
palpi white, speckled and barred with black; terminal joint white, with
two ill-defined black annulations, one around the middle and one just
before the tip; brush short, divided. Face iridescent white. Head and
thorax white, sprinkled with dark fuscous scales. Fore wings clothed
with very long, narrow speckled scales; ground color white, heavily
overlaid with ochreous and fuscous on the basal two thirds of the wing;
the apical third is also sprinkled with dark scales, but to a less extent
and appears quite light contrasted with the basal part. Near base is
an oblique, outwardly directed, black costal streak, reaching the fold
and followed by a white space only slightly sprinkled with dark scales.
There are two longitudinal rows of tufts of raised scales, one through
the middle of the wing with the first tuft at basal third, the second on
the middle of the wing, and the third at the end of the cell; the other
row with two tufts below the fold and the third just below the end of
the cell. Hind wings light fuscous. Legs white, barred with black;
tarsi black, each joint tipped with white.

both by the presence of the tufts of ‘raised scales.
Gelechia triangulella, n. sp.
Antenne purplish fuscous, with black annulations. Second joint of
labial palpi iridescent roseate white, sparsely dusted with dark fuscous
especially on the brush, which is short and divided, longest at base
and tapering towards apex; terminal joint blackish fuscous. Face pale
fuscous, strongly iridescent. Head and thorax dark fuscous. Fore
wings with light fuscous ground color heavily overlaid with dark
fuscous scales, and with a roseate tinge. On the middle of the cell is
a blackish triangular spot with one point touching the fold and pre-
ceded basally by a few ochreous scales; at the end of the cell is a
similar blackish triangular spot; the edges of both spots are faintly
continued to the costal edge. Apical third of the wing heavily overlaid
with blackish scales. Cilia roseate, sprinkled with black scales. Hind
wings light silvery fuscous; veins 6 and 7 nearly parallel, veins 3 and 4
short-stalked. Abdomen ochreous-fuscous. Legs ochreous, mottled on
their outer sides with black scales.
Alar expanse, 12-13 mm.
Bright Angel and Williams, Ariz., June and July (H. S.

Type.—No. 9894, U.S. National Museum.
This is a rather inconspicuous dark species, not very near
to any described American species, but probably most easily
placed with the few other roseate species, from which it is
easily separated -by the two large triangular discal markings.
One specimen bears Mr. Barber’s label, “common in rats’
nest.”
Gelechia kincaidella, n. sp.
Antenne unicolored, dark fuscous. Labial palpi light ochreous, with
base of second joint brown and with outer side and tip of apical joint
slightly shaded with brown; brush on second joint well developed, but
not divided, largest at base, gradually shorter towards apex. Face
whitish ochreous. Head and thorax whitish-ochreous, patagia dark
brown. Fore wings light ochreous, with a slight tendency toward red-
dish in the apical part. Costal base, a large semicircular costal spot
before the middle of the wing, and a large discal spot at the end of
the cell dark brown, with the light ground color as narrow channels
between the spots. The large brown spot at the end of the cell is

me pleasure to dedicate it to the collector.
Paralechia californica, n. sp.
Antenne white, with narrow black annulations. Labial palpi silvery
white; second joint with a small black dot exteriorly; terminal joint
with a black annulation near base and one near the apex; brush well
developed, pure white. Face and head silvery white. Thorax white,
tipped posteriorly with black. Fore wings silvery white, with extreme
base of costa black and with three ochreous oblique costal streaks edged
with black, one of which is rather indistinct near the base, another on
the middle of the wing more pronounced, and one at apical third; these
streaks terminate at about the middle of the wing, except the last,
which runs across the wing. There are six conspicuous tufts of raised
black scales in two longitudinal rows on the middle of the wing. Dorsal
part of the wing pure white, apical overlaid with ochreous and black
scales; the interval between it and the last costal streak appears as a
narrow angulated white fascia. Hind wings light fuscous, cilia yellow-
ish. Abdomen and legs white; tarsal joints annulated with black.

Face black. Head white, with a black dot on vertex. Thorax white,
with black longitudinal central line. Patagia white, with black bases
and tips. Fore wings white, more or less overlaid with fuscous; from
base to apex is a deep black longitudinal central streak; the costal part
of the wing above this streak is somewhat darker than the dorsal part.
The streak is interrupted, though not entirely broken, at the end of
the cell by a pure white dash and it is edged dorsally from base to
beyond the middle by a narrow longitudinal interrupted line of bright
orange scales. A few black scales are scattered over the light portion
of the wing and tend in the apical part to form narrow longitudinal
streaks. Along the dorsal edge is a row of black dots before the cilia,
which are white. Hind wings light fuscous. Abdomen dark fuscous.
Legs black with white annulations.

lepidoptera. The species is nearest Ethmia subcerulea Wal-
singham, but at once distinguished from this and all described
American species of the genus by the prominent central longi-
tudinal black streak.
Ethmia umbrimarginella, n. sp.
Antenne deep purplish black. Labial palpi black; rather more weakly
developed than is typical of the genus and with long spreading brush
of thin black hairs on the second joint. Tongue coiled, black. Face,
head, and thorax deep black. Fore wings dark mouse-gray, with white
costal edge and a central longitudinal streak of bright reddish orange
from base to near the end of the cell. At the end of the cell is a large
oblong deep black spot divided in the middle by a transverse, bright
orange dash. On the middle of the wing just above the longitudinal
orange streak is a small round deep black dot and preceding it below
the orange streak is a larger round black dot. Between this last dot
- and the base of the wing is a short longitudinal black streak edging
the orange. Cilia gray. Hind wings chalky white, with a broad dark

This and the following species belong to the group of the
genus Ethmia which is represented by the European pyrausta
Pallas. The species of this group, which probably should be
given generic rank, differ from the typical species of Ethmia
in the scantier, more hair-like scaling and in the somewhat
shorter and weaker labial palpi, which are not smooth as in
the typical forms, but covered with a more or less strongly
developed brush of thin hairs on the under side of second joint.
None of the hitherto described American species belongs in
this group. The present species is nearest the European auri-
fluella Htibner, but differs in the unicolored abdomen and in
the presence of the orange ornamentation of the fore wings.
This and the following species are at once distinguished from
_all American and European: species by their striking white,
dark-bordered hind wings.
Ethmia coquillettella, n. sp.
Antenne purplish black. Labial palpi black, with base of both joints
white; second joint with short rough brush beneath. Lower part of
face and the region below the eyes white; vertex black. Thorax dark
brown; tips of patagia white. Fore wings mouse-gray, somewhat
lighter than in the preceding species; at base is an inconspicuous light-
yellow spot edged exteriorly with black. Just outside it is a longi-
tudinal deep black dot on the fold and on the middle of the fold is
another similar dot. On the middle of the wing is a third similar
black dot and at the end of the cell is a fourth somewhat larger black
spot, divided in the middle by a large round white or very pale yellow
dot. Cilia concolorous with the wing. Under side of fore wing dark
gray, with the white second discal spot prominently shining through.
Hind wings clear pearly white, with a broad dark gray border on apical
and tornal edges but not on costa nor on the base of the dorsal edge.
Abdomen above dark fuscous, with bright ochreous anal segment;
under side with each joint tipped with white. Legs black, sprinkled
with silvery-white scales; tarsal joints tipped with white.

This species is nearest to the foregoing, but much smaller
and differs otherwise in the shorter brush on the labial palpi,
in the absence of the yellow discal streak on the fore wing,
by the incomplete dark border on the hind wings, and by the
ornamented abdomen and legs. Named in honor of the col-
lector, who has added many interesting species of Microlepi-
doptera to the Museum collection. _

Mompha pecosella, n. sp.
Antenne dark fuscous, with narrow black annulations. Labial palpi
white; second joint thickly sprinkled with black scales, especially on
the exterior side; terminal joint with two black annulations, one near
base, the other just before apex. Face iridescent, white. Head white,
sprinkled with dark fuscous scales. Thorax dark fuscous. Fore wings
blackish brown, irregularly and sparsely sprinkled with white scales
and indistinctly streaked with lighter brown longitudinal lines. From
costal base runs an outwardly oblique ridge of raised scales across the
wing; the basal portion of the wing, limited by this ridge, is strongly
mottled with white scales; just before the middle of the costa begins
another oblique ridge of raised scales, parallel with the first, but not
so complete, consisting of small separate tufts, of which the largest
is on the fold. Below the end of the cell is a large tuft of raised scales,
surrounded by scattered white scales. Hind wings dark fuscous. Ab-
domen fuscous above, ochreous on the under side. Legs blackish,
sprinkled with ochreous.

Pecos, New Mexico, June (T. D. A. Cockerell).
Type—No. ggo1, U. S. National Museum.
This species is quite close to Mompha murtfeldtella Cham-
bers, but it is smaller and the basal part of the fore wings is
mottled, not pure white as in murtfeldtella; the light colored
thorax also distinguishes that species from the present. With
wings folded this insect looks like a Recurvaria.
Mompha iridella, n. sp.
Antenne dark brown, with indistinct silvery white annulations.
Labial palpi white, terminal joint shaded in front and at apex with
golden fuscous. Head and face white. Thorax fuscous, iridescent.
Fore wings light golden brown, overlaid with iridescent white and blue
scales. A triangular spot near base of costa, another on the middle
of costa, and a third larger costal spot between the latter and apex
silvery white; the two last costal spots are edged exteriorly with
blackish scales. Between the fold and the dorsal edge are two or
three small tufts of erect iridescent scales; similar small tufts are
found on the middle of the wing and one at the end of the cell; just
below the latter is a larger dark brown iridescent scale tuft. Tip of
apical cilia white, cilia otherwise light yellowish fuscous. Hind wings

Maxillary palpi yellowish. Thorax and fore wings yellowish fuscous
mottled with black; at basal third of fore wing is a narrow straight
transverse white fascia, edged basally with black; at the middle of the

Type—No. 9903, U. S. National Museum.
Bred by Mr. E. S. G. Titus in the Insectary of the U. S. Be.
partment of Agriculture from an Opuntia received during the
winter of 1904-5. The larva mines just under the epidermis,
making a long winding serpentine mine sometimes widened out
into irregular blotches. The larva, like those of the other
species of the genus, is footless, much flattened and incised be-
tween the joints while in the mine. At the last larval molt it
assumes the cylindrical form with normal legs and spins the
characteristic cocoon with the peculiar globular ornamentations,
as do the other species of the genus.
Ectoedemia, n. gen.
Head and face tufted. Antenne #%, simple in both sexes, rather
thick; basal joint concave and dilated to form a small, strongly scaled

of the wing and approaching each other at apex; vein 2 simple; vein
Ic perceptible. Posterior tibize clothed with stiff hairs above; middle
spurs near but below middle of tibia.
The genus is very close to Nepticula Zeller, but that homo-
geneous genus of leaf-mining moths will not allow the gall-
making populella within its limits. The main structural differ-
ences which separate Ectoedemia are the smaller eye-cap, the
somewhat more strongly developed labial palpi, the closed cell
in the fore wings, and the spurs on the posterior tibie—which
are situated near but below the middle. I am pleased that my
views coincide with those of Dr. Edw. Meyrick, to whom I
showed specimens while at his home in Marlborough.

Massachusetts; New Hampshire. Food plant, Populus.
Type.—No. 9904, U. S. National Museum.
Described from a very large series of moths bred in the in-
sectary of the U. S. Department of Agriculture from galls on
the petiole of leaves of poplar received in September, 1884,
from Miss C. H. Clarke, Jamaica Plains, Mass., and from A.
Koebele at Holderness, N. H. The following are extracts from
Mr. Theo. Pergande’s notes on the species:
Each gall contains a single larva, which when mature is 8 mm. Iong
and pale yellow, with pale brown head, mandibles darker, and posterior
margin of anal shield brown. Legs only rudimentary and can be en-
tirely withdrawn from view.
The gall is almost globular, of about the size of a pea, and is a
swelling of the petiole close to the leaf; it is somewhat rugose longi-
tudinally and of a grayish color. The course of the petiole is gen-
erally very distinct along its upper side, being smooth and of a reddish-
brown or yellowish color. The cavity is more or less irregular on
account of the woody fibers, which run through the walls of the gall
and which are not eaten by the larva. Late in October the larve left

where they spun small brown, flat, oval cocoons, resembling in shape
very much those of the Nepticula on apple. The moths issued during
May of the following year.
Neolophus punctellus, n. sp.
Antennz simple in both sexes, thick, with closely set whorls of short
scales which give an appearance of serration; ochreous gray. Labial
palpi in the males long, slightly recurved, reaching vertex, closely
appressed to the face; in the females much shorter, porrected, terminal
joint deflected. The palpi are slightly lighter than the head and
thorax, which are covered with light fuscous white-tipped scales;
thorax smooth. Fore wings appear pearly, light, whitish fuscous,
irregularly and sparsely dotted with black scales; under a lens it is
seen that the scales are of different shades of brown, each tipped with
very light, nearly white, slate-color, except the few deep black ones,
which are slightly metallic. Cilia blackish brown. Venation normal,
with 12 veins, 7 to termen just below apex, 8 and 9 stalked, 1b furcate
at base. Hind wings ochreous brown, with 8 veins, all separate; 3, 4,
5, 6, and 7 nearly equidistant and parallel from the end of the cell; a ~
forked discal vein to vein 4 and to just below vein 6. Abdomen dark
fuscous above. Under side of body whitish. Legs whitish, sprinkled
with fuscous; tarsal joints dark brown, tipped with white.

The 206th regular meeting was held at the Sengerbund Hall,
314 C street, N. W., the Society being there entertained by Mr.
E. A. Schwarz. In the absence of the president and both vice-
presidents the meeting was called to order by the treasurer,
Mr. Patten, and Mr. Schwarz was elected president pro tem.
The following persons were present : Messrs. Ashmead, Barber,
Barrett, Busck, Condit, Currie, Davis, Heidemann, Knab, Law-
ford, Morris, Schwarz, Stiles, and Ulke, members, and Messrs.
Douglas H. Clemons and William G. Dietz, visitors. The
minutes of the April and May meetings were read and approved
and reports were presented by the treasurer and by the publi-
cation and executive committees.
_ Dr. A. Fenyes, of Pasadena, Cal., and Mr. F. H. Mosher, of
New Bedford, Mass.,, were elected corresponding members.
By vote of the Society Doctor Howard was requested to act
as a delegate from the Entomological Society of Washington
to the meeting of entomologists to be held at Ithaca, N. Y.—in
connection with the summer meeting of the American Associa-
tion for the Advancement of Science—for the purpose of or-
ganizing a society of American entomologists.
The chairman referred to the overwhelming disaster that had
fallen upon the city of San Francisco from the earthquake and
resulting fire and spoke of the almost complete losses of books
and specimens sustained by the California Academy of Sciences
and by Mr. Charles Fuchs, the custodian of the insect collections
of that institution. It was thereupon moved and seconded that
the Society aid in the restoration of the library of the California
Academy of Sciences and of the personal library of Mr. Fuchs

Doctor Ashmead exhibited the worker of a curious ant col-
lected by Mr. O. F. Cook in Guatemala, Strumigenys mandi-
bularis Smith, a cryptocerine. Little is known of the habits of
these small ants, but some of them live in galleries in twigs and
it is not improbable that they are fungi feeders. Mr. Schwarz
stated that the species of Strumigenys found in Guatemala
lives among old leaves on the ground and that the twig-inhabit-
ing species belong to the genus Cryptocerus. One species of
Strumigenys occurs near Washington, in the vicinity of
Bladensburg, Md., among old leaves and in very small colonies,
some 5 or 6 dividuals only being found together. They may
be collected by sifting.
—Doctor Stiles reported the occurrence of the tick Derma-
centor nitens Neumann in this country. Mr. Hunter recently
sent to Washington specimens from Texas. This species has
- heretofore been reported from Porto Rico and South America.
It occurs on horses. Mr. Schwarz remarked that if this species
were native to Porto Rico or the West Indies it must have had
some other host than horses originally, since the horse is not
native there. He asked Doctor Stiles whether this tick had
been found on any other animal, and Doctor Stiles replied that
it had not. Doctor Stiles stated further that while a single
species of ticks might be taken on several different species of
animals, yet in the well studied forms it would appear that there
is a decided predilection for some one host species. Mr.
Schwarz stated that a man-attacking species of tick was very
common in Alta Vera Paz, Guatemala, and Doctor Stiles then
said that this was in all probability Ornithodorus megnini
Dugés.
—Mr. Barber reported having captured a specimen of Manti-
spa brunnea Say, a neuropteroid insect, at Jacksons Island, in
the Potomac River not far below Great Falls, Maryland. Al-
though this species is recorded from New Jersey and Philadel-
phia as well as from the Southern States, in its eastern range,
102 ENTOMOLOGICAL SOCIETY
it has never before been taken, judging from the absence of
confirmatory records, in the vicinity of Washington. When he
first observed it in flight Mr. Barber mistook it for a wasp of
the genus Polistes. The specimen was exhibited.
—Mr. Barber showed also a specimen of Flebotomus, new
species, a small fly belonging to the family Psychodide, from
Guatemala, where he found it extremely annoying from its bite,
which was quite severe. According to Mr. Coquillett this
genus has not before been reported except from southern Eu-
rope and Africa. Mr. Barrett said he believed he had seen the
same fly in the southern part of the State of Vera Cruz, in
Mexico, where it was known as “chaquista.”’. If this were the
same insect he could testify to the severity of its bite.
—Mr. Knab spoke of the paper published by Doctor Dyar and
himself on the classification of the Culicide by larval charac-
ters.*. The paper had been adversely criticized, particularly
because a number of new species were based solely upon larval
characters. While this proceeding might cause temporary in-
convenience to systematists it nevertheless seemed to the
authors the only method of expressing the great importance of °
the larval characters, not only in the separation of species other-
wise hardly distinguishable, but above all in putting the classi-
fication upon a more natural basis. Systematic workers on the
Culicidzee have wholly neglected the study of the early stages
and have based their classification largely upon superficial and
unimportant characters. Many of the genera are unnatural and
often composite, formed of species brought together upon
superficial resemblance but in no wise related. Doctor Dyar’s
work upon the early stages of the Lepidoptera and its influence
upon the classification of that order is so well known that
similar work of his in other groups is bound to command re-
spect. Under the circumstances the following post-card, re-
ceived from Baron von Osten Sacken by Doctor Dyar, is of
interest as coming from a man who can see beyond the inevi-
table shortcomings.
“The larve of Culicide classified as independent organisms. By
Harrison G. Dyar and Frederick Knab. Journ. N. Y. Ent. Soc., Vol.
XIV, pp. 169-230, Plates 1v-xvi, 1906. (Separates issued March 15, 1906.)
OF WASHINGTON. 103
HEIDELBERG, GERMANY, May 4, 1906.
My Dear Sir: I had the pleasure to receive your paper, “ The larvz
of Culicidz classified as independent organisms.” When I first began
the study.of N. Am. Diptera, in 1856, I never dreamed that within half
a century this study would reach a degree of progress and perfection
as your paper shows it to be the case! :
Very sincerely yours,
Gite O73
Mr. Knab then requested Doctor Stiles to state the ruling
adopted by the International Zoological Congress with refer-
ence to species based upon larval characters.
In reply Doctor Stiles said that there were two standpoints
from which to look at this question. The first was that of no-
menclature and from this standpoint he thought the practice of
describing species from other than the adult forms was perfectly
allowable. Numerous species in different groups of the ani-
mal kingdom have been described from some immature stage
and the descriptions and names under which they were pub-
lished have since been recognized as valid. From the stand-
point of classification the question was, however, one of feasi-
bility. In many cases the descriptions of immature stages are
of great value. As an instance, the descriptions of the eggs of
cestodes and nematodes are very important in clinical diag-
noses, and clinical determinations are in these groups made on
the egg nine times out of ten.
Mr. Morris said that it was dasinidty among botanists,
especially among students of fungi, to recognize the earliest
name given to a plant regardless of what stage formed the basis
of the description; and in publications these names were fol-
lowed by Roman numerals to indicate which stage was de-
scribed.
Mr. Schwarz alluded to the recognition of descriptions of
the work of insects, as galls, etc. He asked Doctor Stiles
whether species based on the description of the structure and
form of the excrement should be considered valid. Doctor
Stiles replied that fossils described on the structure of the
excreta or of prints were accepted and he saw no reason why
the same rule should not apply to other animals.
104 ENTOMOLOGICAL SOCIETY
—Mr. Schwarz presented an informal paper entitled ‘‘ Notes
on Guatemala.” He stated, by way of introduction, that Mr.
Barber and he had recently returned from a short trip to
Guatemala for the U. S. Department of Agriculture, most of
their time being spent in the province of Alta Vera Paz.
Guatemala has been more written about than any other Central
American country. Doctor Sapper spent twelve or thirteen
years in Alta Vera Paz and has written a most interesting book
concerning the region. The entire country made up of British
Honduras, Costa Rica, Yucatan, and Panama is one solid
tropical forest. The plateau region of Guatemala, of which
Alta Vera Paz is a part, is drier than the country of the lower
levels and bears some resemblance to the plateau regions of
Mexico and the United States. One peculiarity of Guatemala,
however, is that the mountain ranges run from east to west.
There are three of these ranges, of which the southernmost is
the highest. Some of the peaks are 12,000 or 13,000 feet high
and have never been scaled.
Regarding cotton raising in Alta Vera Paz and the cotton-
protecting ant or kelep (Ectatomma tuberculatum Oliv.) Mr.
Schwarz stated that there was no wild cotton plant in that
country, but some remarkable varieties of cotton are cultivated
there which need no protection whatever from the cotton boll
weevil (Anthonomus grandis Boh.). In Guatemala cotton is
grown continuously and there is no intermittent season as in
the United States. The arborescent cotton found there is not
native and it reproduces throughout the year as do the other
forms of cotton. On this arborescent cotton the boll weevils
multiply and it is this cotton which needs protection from these
insects. In regard to the kelep colonies, some of them are
insectivorous and others not. Those which are insectivorous
will eat any insect which occurs on the cotton, and do not con-
fine themselves to boll weevils.
The amount of rainfall in Guatemala is astonishing, and this
accounts largely for the immense forests. There is a scarcity
of roads and clearings and this makes collecting difficult, as it
is almost impossible to penetrate the tropical jungle.
Large numbers of brillant butterflies are to be seen in the
OF WASHINGTON. 105
clearings, but other insects must be searched for, and to secure
them great labor is required. The diurnal Lepidoptera from
that country are well known; the Heterocera, on the other hand;
are very rarely seen and appear to be very scarce. The fami-
lies of Coleoptera which are well represented are the Chrysome-
lide, the Cerambycide, and the Curculionide. Of these, the
Chrysomelidz are conspicuous and very numerous, both in
species and individuals. The Cerambycidz, although well rep-
resented, are not conspicuous and must be searched for. The
Curculionide, also, are not obvious, but are nevertheless well
represented. There appear to be no large bright colored Dip-
tera. Some Tipulide mimic hymenopterous parasites and are
quite conspicuous. Man-attacking Diptera are very abundant,
and are represented by black flies (Simulium), sand flies, mos-
quitoes, Tabanidz, Hippelates, and the psychodid Flebotomus
exhibited earlier in the meeting by Mr. Barber. Antidotes and
repellents are not of much account against them, and the latter
are soon dissipated in the open air. On the whole Mr. Schwarz
thought that the Diptera were not well represented as regards
number and variety of species. Forficulidze were abundant and
in great variety, as were also the roaches and crickets in the
Orthoptera, and the katydids. Strangely enough they found
not a single native dytiscid beetle. Dragonflies and other in-
sects belonging to the neuropteroid orders were poorly repre-
sented. There was a remarkable absence of fleas, though the -
sand flea (Sarcopsylla) occurred on the sand of the coast at
Puerto Barrios; no bed bug's were seen or heard of, and Mr.
Schwarz stated that the driver ants (Eciton) constituted a
capital enemy of all household insects.
In conclusion Mr. Schwarz exhibited a collection of photo-
graphs of Guatemala scenery taken on the trip by Mr. Barber.
OCTOBER 4, 1906.
The 207th regular meeting was held at the Sengerbund Hall,
314 C street, N. W. President Banks occupied the chair and
there were present Messrs. Barber, Banks, Busck, Caudell,
106 ENTOMOLOGICAL SOCIETY
Currie, Dyar, Gill, Hopkins, Knab, Patten, Piper, Quaintance,
Schwarz, Stiles, and Ulke, members, and Messrs. Marcus Ben-
jamin, C. E. Burden, and C. H. T. Townsend, visitors. -
Mr. Knab exhibited a number of photomicrographs of scales
from the wings of adult mosquitoes of different species, some _
of the latter belonging to supposedly different genera. He
pointed out how unsatisfactory and inadequate is a classification
of genera based on these scale characters and mentioned some
of the errors which have been made by attempting to character-
ize genera from these scales alone,- without reference to the
larve. Asan example, Mansonia fascipes Coq. and Pneumacu-
lex signifer Coq. have larve which appear identical, yet have
adults which can not be associated by scale characters. The
genus Grabhamia of Theobald is a composite genus made up
of unrelated species which happen to have similar scales.
Other instances of this kind were mentioned.
—Mr. Schwarz spoke of the importance of correctly-desig-
nated type localities as an aid in the identification of species
the descriptions of which are inadequate. He then referred to
the difficulty he had experienced in designating intelligibly the
localities in which he had made collections with Mr. Barber the
past spring in the province of Alta Vera Paz, Guatemala, where
settlements are few and many of these consist merely of a few
temporary structures, and are not found on the map and have
no permanent standing. In cases of this kind good photo-
graphs of the localities where collections have been made are
often of considerable value, as they show the character of the
locality, its topography, etc., which mere names of settlements
do not. Mr. Barber took a number of such photographs,
many of which are so characteristic that if seen they would be
recognized by any one who had visited the localities. One of
these, exhibited by Mr. Schwarz, was of the hamlet of Cacao
(fig. 5), located at the foot of the cliff of the Thirteen Water-
falls (Trece Aguas) at an altitude of about 900 feet above
sea level. This locality presents a most remarkable topo-
graphic feature which probably has not its like anywhere else.
Mr. Caudell then called attention to the fact that Morse, in
a recent paper on Acrididz, had published photographs of some
OF WASHINGTON. 107
of his type localities, and Mr. Piper stated that he knew of other
similar instances.
—Mr. Quaintance exhibited a microscopic slide of an Aley-
rodes apparently identical with A. citri R. & H., and coming
from China. It was collected on orange, and this, in his opin-
Fic. 5.—Cacao and the Trece Aguas Cliff in Alta Vera Paz, Guatemala.
ion, gave additional evidence to support Prof. Cockerell’s sug-
gestion that A. citri, the destructive orange white fly of
Florida, is native to China and came originally from there.
108 ENTOMOLOGICAL SOCIETY
Another proof lies in the fact that the insect freely infests the
“China tree” (Melia agederach) and also the Cape Jessamine
(Gardenia jasminoides), the former, at least, being native to
China. :
—Mr. Banks exhibited a box of conopid flies taken within
five miles of Falls Church, Va., and remarked on their great
resemblance to wasps. ‘Thirteen species had been taken, as
follows:
Physocephala tibialis Say. Common.
Physocephala sagitiaria Say. Less common.
Conops xanthopareus Will. Common.
Conops sylvosus Will. Local.
Conops brachyrhynchus Macq. Fairly common.
Zodion fulvifrons Say. Common.
Zodion abitus Adams. Four specimens at Ceanothus.
Myopa vesiculosa Say. A few specimens.
Myopa pilosa Will. Two specimens.
Oncomyia loraria Loew. Rather rare.
Oncomyia abbreviata Loew. Common.
Dalmania vitiosa Coq. One specimen at Ceanothus flowers.
Stylogaster neglectus Will. Many specimens, mostly near Ceanothus
flowers.
Practically all of our species, Mr. Banks stated, favor white
flowers, but a few occur at willow bloom in early spring.
—Mr. Banks recorded also the capture of an uncommon
dragon-fly, Neurocordulia obsoleta Say, near the Chain Bridge,
Virginia, last spring. The species had not previously been
taken in this vicinity.
—Doctor Dyar, under the title “Notes on Mosquitoes of |
California,” read a paper in which he gave an account of mos-
quitoes, mostly from the coast region, collected during the past
summer. The most extensive collections were made in the
vicinity of Los Angeles. On this trip Doctor Dyar collected
also along the Southern Pacific Railway between San Francisco
and Portland and on the Northern Pacific between Portland and
Vancouver, also making a side trip to the Klamath Lake region
of southwestern Oregon, and species collected in these regions
were alluded to incidentally.
In discussing the paper Mr. Schwarz spoke of the change in
OF WASHINGTON. 109
the character of the country in much of the arid portion of
southern California, brought about through irrigation. This,
naturally, has resulted in a change in the character of the mos-
quito fauna and an introduction of new forms. There are por-
tions of California, however, where it will probably never be
possible to irrigate, and where therefore no faunal changes of
this character will occur. Mr. Schwarz mentioned the fact that
the western part of the San Joaquin valley contains several
faunal regions which well deserve an investigation as regards
the mosquitoes and other insects inhabiting them. Mr. Currie
then spoke of having collected and reared, among other species,
Culex tarsalis, Culex incidens, and Anopheles punctipenms and
maculipennis at Portland, Oregon, during the season of 1905.
Anopheles punctipennis was the common Anopheles in the
places where his collections were made, namely, near the Lewis
and Clark Exposition grounds.
—The concluding paper was by Doctor Hopkins, and en-
titled “ Statistical Taxonomy.’ What was meant by this term
was explained by Doctor Hopkins and illustrated by a chart in
which the statistical method was applied to bark weevils of the
genus Pissodes. By a comparison of micrometer measurements
of the length of the beak to the length of the thorax and the
length of the elytra in a number of individuals of each species,
a mathematical formula was obtained which would express the
structural proportions of that particular species. Then, by
comparing the formulas of different species the relative position
of each species in the genus or group would be obtained. This
was illustrated in a chart of the species of Pissodes in which the
application of this method divides them into what Doctor Hop-
kins believed to be natural groups. Doctor Hopkins explained
in conclusion that this method was used by him as a guide to a
natural arrangement of species, but not as a means for their
determination and as merely secondary to other characters. He
called attention to the progressive development of the beak in
Rhynchophora, from the Scolytide, which have a non-rostrate
head, to the species of Balaninus in the Curculionidz, which
have extremely long beaks. This elongation of the beak was
not, he believed, brought about through use or as a result of
110 ENTOMOLOGICAL SOCIETY
specialized food habits requiring a long beak, but was merely
the following out of a dominant tendency to modification along
this line without any apparent necessity therefor; in other
words, it may not be an adaptive character. Mr. Schwarz
asked Doctor Hopkins whether he considered the Brenthidze
and Anthribidze as belonging to the Rhynchophora. Doctor
Hopkins replied that he was uncertain as to the position of the
Brenthidz, but the Anthribidz certainly did not belong to the
Rhynchophora.
NOVEMBER I, 1906.
The 208th regular meeting was held at the Sengerbund Hall,
314 C street, N. W. President Banks presided and the follow-
ing persons were present: Messrs. Banks, Barrett, Busck, Cur-
rie, Dyar, Heidemann, Hopkins, Knab, Morris, Patten, Quaint-
ance, Sasscer, Schwarz, Ulke, and Webster, members, and
Messts. C. N. Ainslie and David E. Lantz, visitors. The
minutes of the October meeting were read and approved. The
Treasurer presented a brief report. The Executive Committee
reported that they had elected Mr. E. A. Schwarz as Editor
and Dr. Harrison G. Dyar as Assistant Editor. At a later
meeting they had decided that the election of these editors was
not to change the status nor functions of the Publication Com-
mittee holding office at the present time.
Prof. E. F, Hitchings, State entomologist, Waterville, Maine,
and Rev. James Hansen, St. John’s University, Collegeville,
Minn., were elected to corresponding membership.
Mr. Quaintance exhibited some masses of larval cocoons of
the codling moth (Carpocapsa pomonella L.), taken from the
floor of an apple storage room in southeastern Nebraska. He
stated that the cracks in the boards of the floor were infested
with thousands of these cocoons made by the hibernating larve.
This illustrated in a striking manner the importance of screen-
ing the buildings in which apples are stored, so that the moths
emerging in the spring can not escape to the orchards.
—Mr. Busck exhibited two California species of the tortricid
genus Hendecaneura Walsingham. This genus was erected
OF WASHINGTON. 111
on three Japanese species and had not hitherto been recorded
from this continent. The males of this genus are remarkable
through having only 11 veins in the fore wings instead of the
usual i2 as found also in the females, the stalked veins 7 and 8
having become coincident in the males. One American genus,
Amorbia Clemens, and two Australian genera defined by Mr.
E. Meyrick—all three containing but few species—were the
only other tortricids known to him that exhibited a similar
reduction in the number of veins in the fore wing.
Mr. Busck said that his studies in this family had led him to
believe that this and other secondary sexual characters, notably
the costal fold, could not be relied on as of generic value and .
that genera which were based on such characters alone would
prove to be artificial. The present genus as well as Amorbia,
however, seemed to be well defined on other peculiarities in the
venation, common to both sexes, but other genera, such as
Eucosma, Lipoptycha, and several others, would have to be re-
arranged in order to bring about a natural system.
Mr. Busck stated that at present the costal fold on the fore
wings of the males was relied upon as one of the primary char-
acters in separating the genera in this family. This, aside from
the resulting unnatural grouping, was a constant inconvenience,
as by it only the males could be classified.
Doctor Dyar said he believed that the initiative taken by Mr.
Busck in the tortricids would have to be followed in other
groups of Lepidoptera by the rejection of genera based solely
or mainly on secondary sexual characters. Mr. Schwarz pointed
out that the more remotely a secondary sexual character is
situated from the true characters, the less value it has in classi-
fication.
Doctor Hopkins said that his study of the secondary sexual
characters in the Scolytidz and Pissodes indicated that without
a detailed knowledge of such characters as represented in allied
species and genera their interpretation and use as generic and
specific characters would lead to much confusion in the future,
as it had in the past. Certain characters, such as the more elon-
gate and slender beak and the seven visible dorsal segments in
the female curculionid, might be important family and even
ie “ENTOMOLOGICAL SOCIETY
superfamily characters; while, on the other hand, certain frontal
and elytral declivity characters in the Scolytide might be re-
versed completely in the same genus and in allied genera. It
was evident, however, that secondary sexual characters were of
great taxonomic value when thoroughly studied and properly in-
terpreted. It would appear that the primary sexual characters
of the reproductive organs, while showing striking specific dif-
ferences in some particulars, often have constant characters in
general structure throughout the genus, while certain lines of
modification would serve to indicate primary and minor di-
visions and their natural position in the classificaton. It should
be remembered that in both secondary and primary characters
similar body structure and similar stages of evolutionary devel-
opment might bring about similar characters in very different
species, genera, and families.
—Mr. Schwarz showed a beaiatiful cluster of microgaster
cocoons from Cacao, Trece Aguas, in Alta Vera Paz, Guate-
mala: They were remarkably fine in texture so that the co-
coons in the mass could not be distinguished. The mass when
found was covered with ants of the genus Monomorium, and
the larva of which the microgaster was a parasite could not be
identified. ‘The mass was afterward placed in a breeding cage
and about 200 parasites emerged. These were submitted for
examination to Doctor Howard, who pronounced them not the
microgaster, nor even a secondary, but a tertiary parasite.
—Doctor Hopkins exhibited specimens of the scolytid beetle
Pagiocerus rimosus Eichh. and of its work in fruit of the red
bay (Persea barbonia) and in the pulp and seeds of custard
apple (Anona glabra and Anona cherimolia), and presented the
following note:
A GENUS AND SPECIES OF SCOLYTIDA HERETOFORE
UNRECORDED FROM THE UNITED STATES.
By A. D. Hopxrns.
In April, 1905, the Bureau of Entomology of the U. S.
Department of Agriculture received specimens of Pagiocerus
rimosus Eichh. from Prof. A. L. Herrera, the entomologist of
OF WASHINGTON. ris
the Mexican Government, with the statement that they were de-
stroying the pulp and seeds of custard apple (Anona glabra
and A. cherimolia) in Yautepec, Morelos, Mexico. The speci-
mens of the fruit sent with the insects showed the burrows of
the beetles in the pulp and seed. The walls of the burrows are
apparently covered with a white substance resembling an am-
brosia fungus. ©
In April, 1906, Mr. H. Pittier, of the Bureau of Plant In-
dustry of the U. S. Department of Agriculture, sent specimens
of the same beetle from Cauca, Colombia, South America, with
a statement that they were found injuring corn, but he failed
to send specimens of the work or to describe its character.
On October 4, 1906, the Bureau of Entomology received
specimens of the same species from Mr. G. L. Fawcett, of the
Bureau of Plant Industry, with numerous injured fruits of the
red bay (Persea barbomia), found at Miami, Fla. Mr. Fawcett
suggested that the insect might prove to be injurious to the
avocado or alligator pear, which also belongs to the genus
Persea. Each fruit shows a single entrance through the thin
pulp and seed, and the inner portion of the seed was partially
or completely destroyed when received, but no evidence of the
immature stages was found. Therefore it may be that the
injury was due to a food habit of the adult, and that the broods
may develop in stems of graminaceous or herbaceous plants,
like corn, cane, palm, etc.
Apparently this is the first record of the food habits of the
beetle and also the first record of a representative of the genus
Pagiocerus in the United States.
Blandford? states that this species appears to be common and
widely distributed in tropical America. Eichhoff® described it
' from specimens received from Cuba. Chapuis® records it from
Colombia, Chile, Brazil, and Cuba. In addition, Blandford re-
cords it from Mexico, many localities in Guatemala, and one
locality in Panama.
The only other described species of the genus is P. cribricollis
Eichh. from Brazil.
The genus Pagiocerus comes near to Cnesinus, which is rep-
resented in North America by C. strigicollis Lec., and is widely
distributed in the Eastern and Southern United States, and
extends into Mexico. This species has been found by Mr.
Schwarz boring in the wood of sweet gum (Liquidambar) and
the writer has found it in stems of the large smilax or green-

114 ENTOMOLOGICAL SOCIETY
briar and a correspondent reports finding it in apple branches
in West Virginia. Mr. Fiske found it at Tryon, N. C., boring
in the pith of hickory twigs, and at New Landing, S. C.,
abundant in the stems of smilax. It appears that the larva has
not been observed, therefore the breeding habits of this species
are uncertain.
Doctor Hopkins showed also specimens of the Cnesinus
mentioned in the preceding note, and drawings of structural
details of the Cnesinus, the Pagiocerus, and the hickory bark-
beetle (Scolytus quadrispinosus Say).
—Mr. Schwarz reported that he found adults and larve of
the cabbage butterfly (Pontia rape L.) present in hundreds at
Trece Aguas, Alta Vera Paz, Guatemala, last spring. This
butterfly does not seem to have been recorded from Guatemala
and it was an interesting subject for conjecture how it reached
this rather inaccessible part of the country. Very little vege-
table produce comes to Guatemala from the United States, most
of it being imported from Germany, and it would seem that the
latter country must prove to be the source of the infestation.
Mr. Schwarz described the exceedingly mountainous character
of the country in Guatemala.
—Mr. Quaintance asked the opinion of the members as to
the function of the cornicles or nectaries of the Aphidide. He
stated that David Sharp, in the portion of the Cambridge
Natural History treating of insects, says that although, it was
formerly supposed that the honey dew is excreted from the
nectaries it is now known that this is not the case, but that this
substance is excreted from the anus. Mr. Quaintance stated
that he had himself observed globules exuding from the necta-
ries of the cabbage aphis (A. brassice L.), the apple aphis
(Aphis malt Fab.), and the red goldenrod aphis (Siphonophora
rudbeckie Fitch). Mr. Pergande, too, had informed him that
he had often seen globules of liquid exuding from the nectaries
of aphides of many species—not only from those having exter-
nal tubes but also from those in which the place of the tubes is
taken by two simple openings or pores—and in making balsam
mounts of aphides from life he had seen drops of fluid exuding
OF WASHINGTON. 115
from the tubes and pores and other drops about to exude. Mr.
Pergande also informed him that in the case of those gall-mak-
ing aphides in which no tubes or corresponding pores have been
discovered he had noticed drops of liquid in the galls which
must have come from the anus.
The matter was discussed by several of the members present
and the consensus of opinion was to the effect that while liquid
is excreted from the anus yet it is excreted also from the
nectaries, and many of the members stated that they had
observed the fluid coming from the nectaries.
—Mr. Knab exhibited the volume for the year 1760 of the
French journal “ Memoires de Mathematique et de Physique,”
and called attention to an article published therein describing
the copulation of mosquitoes. The observations there recorded
were made by the commanding officer of a ship in passage from
India around the Cape of Good Hope, and from the description
of the act it was now possjble to recognize the species involved
as Stegomyia calopus. ‘The copulation was observed after the
vessel had been on its way some months and had rounded the
Cape, and after storms, indicating that the mosquitoes were
breeding on the vessel. The act took place in flight, but there
was no swarm and the sexes faced each other and clasped each
other with their claws. This agreed with what is now known
of the habits of Stegomyia. Mr. Knab stated that the mosqui-
toes recorded in this article as very abundant on board the vessel
early in the voyage were probably not Stegomyia but Culex,
and these no doubt perished, while those seen abundantly later,
and whose copulation was observed, were Stegomyia and were
undoubtedly bred on board the vessel. Mr. Knab pointed out
that there are two styles of copulation among mosquitoes and
these are correlated with the structure of the claws of the
female; the mosquitoes which copulate as described for
Stegomyia have toothed claws in the female, while those in
which there is a swarm of males into which the female flies
and where the sexes are joined end to end and facing in oppo-
site directions, in the fashion of the Tipulidz or crane-flies,
have simple claws in the female. This character of the toothed
or simple claws is not one which has any importance in classi-
116 ENTOMOLOGICAL SOCIETY
fication. Mr. Schwarz related instances of the carriage and
breeding of Stegomyia on board ship.
—Mr. Banks recorded the capture at Glencarlyn, Va., of
the rare syrphid fly Mixrogaster breviventris Kahl. The species
was described from Kansas.
—Mr. Schwarz mentioned as an interesting fact that the
collection of large tenebrionid beetles of the genus Eleodes
sent from the National Museum to Dr. F. E. Blaisdell of San
Francisco was entirely uninjured by the earthquake, and the
specimens were so returned to the National Museum. Although
the shock threw the boxes all together in a heap yet not a tarsus
was lost. Doctor Dyar stated that the collection of Lycznide
of the National Museum sent for study to Mr. Fordyce Grin-
nell, Jr., Palo Alto, Cal., was also uninjured by the earthquake.
—Mr. Schwarz presented a paper on the coleopterous fauna
of Alta Vera Paz, Guatemala. He stated that this portion of
Guatemala had been explored by Godman & Salvin for the
Biologia Centrali-Americana and later by Champion, the latter
spending four years there. He and Mr. Barber made collections
in that region last spring while on a mission for the U. S. De-
partment of Agriculture. Large Coleoptera did not appear to
be abundant. About 1,200 species of the order were collected |
by them in that restricted locality alone. ‘The insect collections
which they made at the coast town of Livingston were of quite.
a different character from those made at Cacao in Alta Vera
Paz and from those described in the Biologia, and resemble
specimens recorded from British Honduras.
Mr. Knab remarked that in the tropics the dung beetles of
the genus Onthophagus are often seen resting on the leaves.
Mr. Schwarz stated that Limnichus in the Byrrhide and
Pederus and certain other staphylinids, which live on the
ground along river banks in the United States, live in trees in
Guatemala, the necessary moisture for them being found there.
Mr. Schwarz stated that he and Mr. Barber were under
great obligations to Mr. O. F. Cook and Mr. F. L. Lewton, of
the Bureau of Plant Industry, for procuring for them with
great labor the flowers of some palms in which many fine
insects were found.

- DESCRIPTIONS OF NEW TRICHOPTERA.
By NATHAN BANKS.
(Plates vir, 1x.)
The following pages contain descriptions of thirty new cad-
dice-flies from the United States, a generic synopsis of the
family Sericostomatidz, and an arrangement of the species of
the genus Neuronia. Several new genera in the Limnephilidz
are described; these will be tabulated in a future paper on the
classification of this family. The whole is preliminary to a
catalogue of the Neuropteroid insects of Boreal America, to
be published in a short time.
Phryganea californica, n. sp.
Head yellowish brown, with white hair; thorax blackish, with white
hair and black bristles; a tuft of black bristles at base of fore wings;
the white hair forms a broad median stripe on the thorax; abdomen
brown, banded with yellowish or whitish above; legs pale yellowish, —
with only a very few pale yellowish spines on the tibiz, anterior tibiz
rather infuscated at tips. Wings uniformly blackish fumose, densely
clothed with long black and white hair intermixed, darkest along the
basal venation; an elongate white spot on the thyridium before fork,
a white dot in base of third apical cell, the cross-vein at base of the
fourth apical cell, and the lower part of the arculus hyaline. Both
wings very narrow and almost acute at tips, the outer edge in fore
pair being straight, not convex, a distinct cross-vein between costa and
subcosta near pterostigma; discal cell plainly shorter than its pedicel;
first apical sector arising from about middle of cell; the apical cells
long and narrow; the arculus straight. In the hind wings the discal
cell is very short, not one-third the length of the second apical cell,
fifth apical cell very short pedicellate; no cross-vein from radial sector
to radius.

118 ENTOMOLOGICAL SOCIETY
with short black hair. In fore wings the first apical sector arises
before the middle of discal cell, the latter scarcely as long as its pedicel
and narrowed at tip; the radius downcurved and then upcurved
before the pterostigma; arculus nearly straight, not angulate at end of
cubitus, but the branch from median is angulate to meet the arculus.
In hind wings there is a cross-vein from discal cell to radius, and the
first sector arises from the middle of this cross-vein; the discal cell
is very short, the third apical cell narrowed at base. The tibie of
legs have only a few short black spines; those on the hind tibiz not
more than one-half the diameter of the joint.

pedicellate; lower branch of radial sector ending slightly before tip
of wing.
Expanse, 16 mm.
Three from New Haven, Conn., 23 June (Viereck) ; also
from Falls Church, Va.
Cecetina inornata, n. sp.
Yellowish, clothed with yellow hair; palpi with more gray hair;
antenne narrowly annulate with dark; abdomen and legs entirely pale
yellowish. Wings hyaline, densely clothed with golden, and some
blackish hair, apical fringe rather long, and brown; anostomoses not
marked, the posterior one very oblique; hind wings more hyaline, with
sparse blackish hair, and long dark fringe. Maxillary palpi rather
heavy, and densely haired. Fore wings with both forks not extending
back of discal cell; in hind wings the second fork has a pedicel nearly
its length, and the first fork extends only a short distance back on the
discal cell.
Expanse, 18 mm.
Douglas, Ariz., August (Snow).
OF WASHINGTON. 129
C£cetina apicalis, n. sp. (PI. VIII, fig. 2).
Yellowish, clothed with yellowish hair; palpi with darker hair;
antennze annulate with black; abdomen pale above, almost black be-
neath; legs pale yellowish. Wings very sparsely clothed with very
fine black and yellow hairs; the anastomoses broadly margined with
black, the posterior one running obliquely backward; membrane toward
apex is blackish; hind wings more hyaline, with a long black fringe on
posterior margin, especially heavy near base. Maxillary palpi heavy,
and densely haired. Fore wings nearly acute at apex, both forks barely
reaching back of the anastomosis; in hind wings the second fork starts
from the discal cell, the first extending back a considerable distance on
the cell.
Expanse, 18 mm.
One specimen from Brownsville, Tex., June (Snow).
(Ecetina persimilis, n. sp.
In appearance this species is very like unto C. incerta and G&. parvula,
and about intermediate in size, or as large as a small CZ. incerta. The
wings are clothed with long gray hairs, and the anastomosis is dark brown.
It belongs, however, to the other section of the genus; having in the
hind wings the cross-vein connecting fork 1 to fork 3; so it is more
allied to CG. fumosa. It differs, however, from that species in smaller
size, lack of patches of black hair on the wings, and in that the cross-
vein closing the discal cell is as long as the next cross-vein beyond it
(plainly shorter in CG. fumosa).
Specimens from High Island, Maryland, and from Glen-
carlyn, Va., in June.
The genus Ccetina differs from the European Cécetis (type
ochracea) in having much narrower hind wings, and in that the
cross-vein at end of discal cell of fore-wing is considerably be-
yond the other cross-veins. The European @. lacustris, and
probably other species, belongs to CGécetina. The species of
(Ecetina may be arranged in two sections, according to position
of the cross-vein in the hind wings. In one section the cross-vein
connects forks 1 and 3, while in the second section the cross-
vein ends in the median before the origin of fork 3. The first
section includes CG. fumosa, avara, apicalis, and persimilis; the
second section contains incerta, flavida, guttata, floridana, in-
ornata, parvula, and flaveolata.
Setodina, n. gen.
A leptocerid near Setodes, but the last joint of the maxillary palpi
is short, although a little curved; the spurs are 0-2-2; forks 1 and 3
130 ENTOMOLOGICAL SOCIETY
are present in the fore wings, I and 5 in the hind wings; there-is no
cross-vein in the hind wings; antenne much longer than the body,
basal joint very large. Based on a tiny insect, no larger than a good-
sized hydroptilid, which differs from all other Leptoceride in the
greatly reduced venation of the hind wings.
Type: The following species.
Setodina parva, n. sp. (Pl. IX, figs. 24, 26).
A uniform dull pale gray; legs and antenne more yellowish; wings
clothed with gray hairs. Fore wings quite slender; the radius and
subcosta close together; the discal cell longer than second apical cell;
the cross-veins are very faint, but can be seen against a strong light;
hind wings with a long fringe behind, no cross-veins present; in the
basal part of third apical cell of the fore wings there is a small dark dot.
Expanse, 5.5 mm.
Three specimens from Kissimmee, Fla., in November.
Hydropsyche minuscula n. sp. (Pl. VIII, fig. 5).
Dull black, head and thorax clothed with yellowish gray hair, almost
golden on vertex, with some black hair each side; antenne pale, annu-
late with dark; abdomen blackish above, yellowish below; legs yel-
lowish, with yellow spurs, some longer black hair on hind tibiz. Wings
clothed with black and yellowish hair, giving them a uniform grayish
or brownish appearance, devoid of markings, except sometimes:a little
more heavily marked with black on the middle of the hind margin, and
sometimes a faint yellowish mark near outer anal angle; fringe blackish,
or broken with yellow near outer anal angle; hind wings gray, with
gray fringe. Eyes of male widely separated; antenne rather heavy;
fote wings broadly rounded at tips, fork I reaching more than one-
half way to discal cell; in hind wings fork 1 is absent, and the tip
is slightly upturned.
Length, 6 mm.
Several specimens from Plummers Island, Maryland, in
August.
It falls in Ulmer’s genus Hydropsychodes, which differs from
Hydropsyche only in lacking fork 1 to hind wings; H. analis,
H. sordida, H. gracilis, and H. divisa will also go in this genus,
if it be adopted.
Phylocentropus, n. gen.
An hydropsychid near Holocentropus; venation as in that genus ex-
cept that fork 1 in both wings arises from the discal cell; in this
OF WASHINGTON. 131
respect like Wormaldia. Forks 1, 2, 3, 4, 5 in fore wings; I, 2, 3, and
5 in hind wings. Fore wings with distinct costal cross-vein; discal cell
closed in both pairs of wings; spurs 3-4-4; tibia and metatarsi of
middle legs dilated in female; no ocelli.
Type: Holocentropus placidus Banks.
The genus also includes Polycentropus lucidus Hagen.
Nyctiophylax Brauer.
This genus includes Polycentropus vestitus Hagen and
P. affinis Banks; and it is probable that Cyrnus pallidus Banks
and C. fraternus Banks also belong here; they have the super-
ior branch of radial sector present in hind wings, but the
closure of the discal cell is extremely indistinct, if always really
present.
Plectrocnemia australis, n. sp. (PI. IX, fig. 17).
Face below antenne deep black, with black hair; palpi black; head
above antennze with much golden hair, but a tuft of long, black hair
above each eye; antennz yellow, faintly annulate with pale brown;
thorax with a stripe of yellow hairs in the middle, and black hair on
each lateral lobe; abdomen brown; legs rather brownish yellow. Wings
brown, thickly spotted with yellow, median vein and anal region darker
brown than elsewhere, a patch of longer black hair near base of fore
wings, and several black marks along the costa. Hind wings grayish
hyaline, darker near tips on costal part. Venation like P. conspersa,
but fork 1 is not nearly as long as its pedicel; fork 5 is wide-spread at
base. The legs are long and slender; on middle tibie the submedian
spurs are as far from base as the longer spur of the pair; on hind
tibize the submedian spurs reach scarcely more than one half way to
tip; and the apical spurs are hardly one half the length of the first
tarsal joint. The tip of female abdomen ends in a slender upcurved
ovipositor, widened at tip.
Expanse, 2I mm.
From Jacksonville, Fla. (Mrs. Slosson).
Psychomyia meesta, n. sp. (Pl. VIII, fig. 9; Pl. IX, fig. 15).
Head and thorax black; vertex with white hair, and some white hair
near the tubercled pits on mesonotum; antenne pale yellowish; palpi
brown, with black hair; legs pale yellowish, with large, long spurs,
2, 4, 4, no trace of another on front tibie; all legs with many fine
yellowish hairs; abdomen brown, appendages yellowish; wings dull
brownish, without mark, densely black-haired, but these hairs most
prominent along anal field where they are nearly distinct enough to
132 ENTOMOLOGICAL SOCIETY
form a stripe. Fore wings veined as in Psychomyia, fork 1 not present;
hind wings more excavate on apical half of front margin than any
figured species, and fork 3 is not present, thus like Ecnomus; fringe
on hind edge of hind wings about as long as width of wirtg; middle
tibiz and metatarsi plainly dilated in female,
Expanse, II mm.
One female from Colorado (No. 21 33), probably Ft. Collins
or Denver.
Biyacosiila torva Hagen (PI. IX, fig. 16).
In the Eastern States there are at least three allied species. I
identify as R. torva a form with more spotted wings than the
others. It has the lower branch of the median vein in fore
wings forked before the middle, so that the fork is longer than
its pedicel ; this fork is not as near base as the fork of the upper
branch of the radial sector. The male genitalia show a forked
process each side below.
I have specimens from Sherbrooke, Canada; Franconia,
N. H., and Sea Cliff,-N; Ys
Rhyacophila terminata, n. sp. (Pl. VIII, fig. 7).
In this species the lower branch of the median vein in fore wings is
forked much beyond the middle, so that the fork is much shorter
than its pedicel, and no longer than the fork of the upper. branch. The
wings are not very dark, rather sparingly flecked with yellow, and
the basal joint of the antennze is much darker than the others. The
male genitalia show a pair of very long appendages below.
From Delaware Water Gap, New Jersey. Two females
from Ithaca, N. Y. agree in venational characters, but are in
poor condition.
Rhyacophila nigrita, n. sp.
Much like R. torva; with the fork of lower branek of the median
vein before the middle, so that the fork is longer than the pedicel?
this fork is as near to the base of wing as the fork of upper branch
of the radial sector. Wings a deeper black than in R. torva.

NOTES ON UNITED STATES ORTHOPTERA, WITH THE
DESCRIPTION OF ONE NEW SPECIES.
By A. N. CAuDELL.
In June, 1905, Dr. J. Hornung, of Menlo Park, Cal. sent to
the National Museum several specimens of a large black earwig
for determination. These proved to be Chelisoches morio
Fab., an insect hitherto unknown from the United States.*
Correspondence with the collector elicited the information that
they were taken some miles from Menlo Park in peach trees.
They are probably importations from the Hawaiian Islands,
where the species is common.
On May 18, 1906, Mr. Douglas Clemons found a single
specimen of the small cockroach Holocompsa nitidulus Fab.,
in Washington, D. C. It was crawling on cotton batting from
“In 1900 (Ann. Soc. Ent. Belg., xtiv, p. 51) Burr records it as ques-
tionably occurring in North America.
134 ENTOMOLOGICAL SOCIETY
the store room at the National Museum. This handsome little
roach is found in the West Indies and Mexico, as well as in
Central and South America. The members of the genus are
easy of dissemination and are fast becoming cosmopolitan,
and one or more species will very surely become permanent
residents within our borders.
On October 9, 1905, Mr. J. C. Rounds, of Westwater, Utah,
sent a female specimen of Stagmomantis carolina L. to the
National Museum for determination. This, I believe, is the
farthest western specific record for this insect, though some
older general localities may include regions even farther west.
The writer has in preparation a catalogue of the Orthoptera
of the United States and Canada which is intended for publica-
tion as soon as Professor Bruner completes his work on the .
Biologia Centrali-Americana, which includes many species that
occur within our borders. The advancement made in the study
of this order since the issuance of Scudder’s catalogue seems
to warrant a new catalogue being made. Certain names in
present use that are untenable from one cause or another, usu-
ally nomenclatural in nature, will need changing. One such
case follows:
Scudder? describes what he supposed to be the Caloptenus
regalis of Dodge, placing it in the genus AZoloplus. But, as
stated by Professor Bruner in a letter to the writer, the C. rega-
lis of Dodge is a Melanoplus occurring in Nebraska and Colo-
rado, specimens from the latter State sent me by Professor
Bruner agreeing with the original description of Dodge.
Thus the insect described as an AXoloplus by Scudder is, from
a nomenclatural standpoint, without a name. The specific
name bruneri is therefore proposed for it.
Asemoplus rainierensis, n. sp.
Last year Mr. H. E. Burke brought me a pair of a new
species of Asemoplus from Mt. Rainier, Washington. This year
(July, 1906)I visited Mt. Rainier and found the insect present
in Paradise Valley in vast numbers. So numerous, indeed,
were they that the ground in places was fairly swarming with
them, the grass and small plants being wholly destroyed by the
myriads of these small grasshoppers. Associated with the new
species was an equal number of an apterous species which was
described by Walker from Canada as A. nudus. Superficially
the new species bears a very close resemblance to Walker’s
species but structurally it is quite distinct. From Asemoplus
montanus Bruner, however, the new species is less easily sepa-

rated. When compared directly with the types of this last
species, however, it is seen to be amply distinct. The three
species of the genus may be separated as follows:

2. Cerci of the male about two and one-half times as long as the basal

convex, passing insensibly into the lateral lobes without indication
Of Interal caringe =) 2.4 chen Ph cra wos ote con's bonnes montanus Bruner.
Cerci of the male no more than twice as long as the basal width,
scarcely attaining the tip of the supra-anal plate and in no way
apically decurved; pronotal disk of both sexes transversely less
convex above, passing more abruptly into the lateral lobes, forming
distinct but rounded lateral carine............. rainierensis, N. sp.
In coloration rainierensis is similar to montanus, except that the
infuscation on the lateral lobes of the pronotum does not extend so
far downwards, making a more distinct lateral stripe. The abdomen
above is usually broadly yellow, rarely with a narrow broken dark
median line. The frontal costa of the female is more distinctly sulcate
than in montanus, and the eyes are not so widely separated, the inter-
space being about three times as broad as the basal segment of the
antennez, while in montanus it is about four times as broad. The pos-
terior margin of the pronotum is angularly concave, much more so,
especially in the female, than that of either montanus or nudus.
The measurements of a mature pair chosen as types from a large
number of specimens are as follows: Length, antenne, male and female,
7 mm.; pronotum, male, 3.5 mm., female, 4.5 mm.; posterior femora,
male, 9 mm., female, TI mm.
Type.—No. 10707, U. S. National Museum.
There is little variation in size. The color of living speci-
mens is very different and much brighter than that of speci-
mens preserved either pinned or in spirits, no matter how well
prepared by stuffing.
Out of nearly one hundred specimens of both sexes ex-
amined, but one specimen was found with either elytron miss-
ing, that one a female with the left elytron gone. Professor
Scudder states that one half or more of all specimens of
montanus seen by him had one of the tegmina gone. This is
not true, however, of the few specimens of that species seen
by me. 3

A FEW NEW COLEOPTERA OF THE GENUS BITOMA,
WITH NOTES ON OTHER COLYDIIDZE.
By CHAS. SCHAEFFER.
This paper is based largely on the material in the genus
Bitoma contained in the Hubbard & Schwarz collection of
Coleoptera in the U. S. National Museum. Through the kind-
ness of Mr. Schwarz I have been enabled to study this material,
and, as will be seen in the following pages, several of the
species have proved to be new. Among the material sent me
by Mr. Schwarz are two more species which are apparently
new, but as I was unable to find a good structural character to
separate them from their nearest allies, and as they were repre-
sented by single specimens only, I leave these for the future,
when more material will be available.
The sculpture of the metasternum of most of our species of
Bitoma may be called granulose. In some species the granules
are distinct, but slightly elongated; in others they are longitu-
dinally confluent, giving the surface a strigose appearance which
is especially strongly pronounced in ornata, quadriguttata and
pinicola, but in vittata more feebly and the granules hardly
confluent. In discolor the sculpture of the metasternum is
feeble, but slightly more distinct than in prosopis and suffusa.
The sculpture of the elytral intervals in pale specimens looks
at first entirely different than in dark specimens of the same
species ; this is rather misleading, especially as in certain species
the sculpture in dark specimens is more difficult to make out
_ clearly than in pale specimens.

ing the apex. Head granulate, finely and sparsely pubescent, ninth
. joint of antennz not wider than the eighth. Thorax broader than long,
distinctly narrowing to base, apical angles not prominent, side margins
finely crenulate, disk with two coste on each side, the inner not as
distinct as the outer, surface granulate. Elytra distinctly broader than
the thorax at base, with three discal and one submarginal coste, which
are sparsely pubescent with short pale hairs; intervals with two rows
of tubercles, the two rows of tubercles separated by a nearly smooth,
longitudinal median space. Metasternum not coarsely granulate, the
granules slightly longitudinally confluent; abdomen feebly punctate and
sparsely pubescent.
Length, 2.75 mm.
138 ENTOMOLOGICAL SOCIETY
_ Brownsville, Tex., one specimen in the Hubbard & Schwarz
collection, collected by Mr. E. A. Schwarz.
Type—No. 10443, U. S. National Museum.
This species has the thorax more distinctly narrowing to base
than any other species known to me, which character, together
with the elytral sculpture and markings, makes it an easily rec-
ognizable species.
I have taken a specimen in Brownsville which is reddish
testaceous, with suture and side margins slightly infuscate, but
which does not differ otherwise; this is evidently not fully
colored yet.
Bitoma pinicola, n. sp.
Elongate, depressed, form of quadriguttatus Say, but slightly broader,
more depressed, the markings at best feebly defined and slightly dif-
ferent in position. Head opaque, black, paler at apex, granulate and
very sparsely pubescent. Thorax broader than long, sides slightly
arcuate, margins feebly crenulate, disk on each side with two costz,
the outer distinct, the inner feeble and obliterated near apex; surface
granulate, piceous and scarcely pubescent. Elytra scarcely wider than
the thorax, disk with four slightly elevated costz, intervals with two
rows of coarse punctures, which are scarcely confluent; color piceous,
with four not very well defined red markings on each elytron, of which
a narrow oblique humeral and an apical rounded spot are more visible
than the two others; one of them is situated near side margin between
the humeral and subapical spot and the other slightly below the sub-
apical, the latter at about apical third. Body beneath and legs piceous;
metasternum longitudinally strigose.
Length, 3 mm.
Lakehurst, N. J., on pine.
This species resemblés guadriguttatus, but is broader, more
depressed, the elytral sculpture not as coarse as in that species ;
the position of the subapical spot is different, which is in
quadriguttatus oblique and slightly behind middle, in pinicola,
when present, apparently rounded and at apical third and the
thoracic costz, especially the inner, are never as distinct as in
quadriguttatus. In the type the markings can be traced and
are as above described; in a few others the markings are either
absent or only the humeral and subapical can be feebly seen.
Bitoma discolor, n. sp.
Elongate, depressed, opaque, pale rufotestaceous; head, thorax, four
spots, and apex of elytra darker. Head finely granulate, sparsely
pubescent; antennze with ninth joint not wider than eighth. Thorax
OF WASHINGTON. 139
nearly as long as broad, feebly narrowing to base, apical angles dis-
tinct, basal angles rectangular, base feebly lobed, side margins irregu-
larly crenate, disk with four coste as in quadriguttatus, surface granu-
late. Elytra slightly wider than the thorax at base, with the usual
four coste, which are very prominent and slightly crenate at their
summit; intervals with two rows of well separated round perforate
punctures, separated by a broad, nearly smooth, longitudinal median
line; color rufotestaceous, with darker markings as follows: One at
scutellum, one slightly below middle at suture, one on each side near
side margin, between the scutellar and sutural spot and apex more or
less piceous. Metasternum and abdomen obsoletely punctate and sparsely
pubescent.
Length, 2.75-3 mm.
Biscayne Bay and Key West, Fla.; Cayamas, Cuba. For
the Biscayne Bay specimens I am indebted to Mrs. A. T.
Slosson ; the Key West and Cayamas specimens were collected
by Mr.-E. A. Schwarz.
Type.—No. 10445, U. S. National Museum.
The apical dark elytral space is variable in extent and is con-
nected in some specimens with the marginal spots. The elytral
spots in some specimens are darker than in others. The color-
ation, as well as the sculpture, distinguishes this species readily
from any of our species.
Bitoma prosopis, n. sp.
Elongate, piceous, opaque, sparsely pubescent; elytra with four not
clearly defined reddish spots, two occupying basal third, leaving suture
and sides narrowly piceous and two near apex. Head nearly smooth,
opaque, sparsely pubescent; antennal club two-jointed; clypeus cover-
ing the mouth parts. Thorax slightly broader than long, apex and base
equal, feebly arcuate at sides, side margin finely crenulate, the inner
of the two lateral coste nearly obsolete, disk finely granulate and
sparsely pubescent. Elytra very little wider than the thorax at base,
with four elevated discal coste, which on their summit are slightly
crenulate and clubbed with short white hairs; intervals with rows of
large coarse punctures, more or less transversely confluent, giving them
a rugulose appearance. Body beneath ferruginous, opaque; metas-
ternum and abdomen feebly punctate and sparsely pubescent.
Length, 2 mm.
Two specimens, one from New Braunfels, Tex., in Coll.
Dietz, the other from San Diego, Tex., in the Hubbard and
Schwarz collection, U. S. Nat. Museum; the latter was col-
lected May 23 by Mr. E. A. Schwarz, whose manuscript name
I have used.
140 ENTOMOLOGICAL SOCIETY
Type.—No. 10444, U. S. National Museum.
This species can only be compared with the darker specimens
of suffusa Casey, from which it principally differs in smaller
size, coarser sculpture of the elytral intervals, and longer cly-
peus, which covers the mandibles completely, the latter always
more or less visible in suffusa.
Bitoma suffusa Casey.
Mr. Schwarz is of the opinion that this species is synony-
mous with gracilis Sharp. This view is very likely correct,
but the description is not sufficient to identify the insect with
certainty, and as some of the species are very close I retain
for the present Casey’s name for this species.
A few specimens before me, collected by Mr. Schwarz in
Yuma, Ariz., are slightly larger, darker in color, and in some
the sculpture of the intervals is coarser, but I am not able to
find at present a good character to separate these from the
lighter colored specimens.
Phlzeonemus catenulatus Horn.
P. adherens Sharp.
Mr. Schwarz suggested the above synonymy to me. The
description and excellent figure of the Guatemalan insect agree
so well in every respect with our species that there is no doubt
of the correctness of this view. A few specimens occurred at
Brownsville, Tex., with the typical form, with which they
agree in every respect except that the elytral costz are several
times interrupted; these may be Reitter’s interruptus, which
is said to be 7 mm. long, while my largest specimen is 5 mm.
Lithophorus succineus Pasc.
I bred a few specimens of this fine species from branches of
Acacia flexicaulis, and also obtained some by beating. The
genus Lithophorus is a member of the tribe Bothriderini and
differs principally from the two genera in our fauna by the
form of antenne; the joints 7, 8, and 9 slightly increasing in
width, 1oth much larger than the 9th, 11th very small, hardly
visible. The species is black, nearly of the form of Bothrideres
geminatus, but larger and more convex; thorax uneven, with
a depression at middle and tuberculate at sides, the third and
fifth elytral intervals with interrupted coste, each costa at
middle with a transparent yellow spot, “like a jewel or piece

Lobogestoria gibbicollis Reitter.
Aditoma bifida Casey.
Looking over some Cuban coleoptera in the National Mu-
seum with Mr. Schwarz, I recognized in Lobogestoria gibbi-
collis what I had identified as Aditoma bifida. Mr. Schwarz
kindly gave me a Cuban specimen for comparison with my
insect, which is from Louisiana, but I was unable to find any
character to separate the two. Reitter described his species as
a lathridiid on account of the three-jointed tarsi, of which no
mention was made by Major Casey in the description. Casey’s
specimen came from Florida.
A WONDERFUL NEW BEETLE OF THE GROUP COPRIS.
By Epwarp A, KLAGEs.
Tetramereia, n. gen.
Form rounded; legs strong. Head clypeate; thorax wider than long,
broadest before middle; elytra subtruncate; metasternum rhomboidal
(as in Phaneus MacLeay), not projecting anteriorly (a character of
Oxysternon Castelnau). Antenne nine-jointed, the first joint of the
club roundly infundibulate and receiving the others. Tarsi four-jointed,
widely flattened, edged with moderately short, stiff hairs, and with
the superior surface inclined toward the center of the body; the first
joint as long as the rest of the foot, the second joint half as long as
the first, the third joint scarcely longer than the fourth; the first three
joints as wide as long and somewhat reniform; the claws and anterior
tarsi wanting. Fore tibie with a movable, terminal spine and with the
outer edge toothed; the hind tibiz with a single terminal spine, the
middle and hind tibie expanding to apex.
Type: The following species:
Tetramereia frederickii, n. sp.
Brown-black; head and thorax rather densely punctured, becoming
rugose on front; clypeus emarginate, with two rounded teeth; thorax
with median lateral impression, and with the basal portion feebly im-
pressed on medial line; elytra rather deeply striate and finely punc-
tured; front tibize four-dentate, the outer three teeth large.
Length, 15 mm.

Type.—Collected by the author and forming part of his
collection.
Named in memory of my brother, Frederick W. Klages,’
who died Mar. 28, 1886, at the age of 27 years.
The specimen above described is seemingly a small female.
The head has the rudiments of a horn and the thorax has a
transverse ridge near the front margin. Analogous processes
are observable in small females of certain species of the genus
Phanzus, to which this is very closely related.
DECEMBER 6, .1906. |
The 209th regular meeting was held at the residence of
Dr. C. W. Stiles, 1412 Hopkins street, N. W..- President
Banks occupied the chair and the following persons were pres-
ent: Messrs. Banks, Barber, Burke, Busck, Caudell, Currie,
Davis, Dyar, Fiske, Gill, Heidemann, Hopkins, Howard, John-
son, Knab, Marlatt, E. F. Phillips, Reeves, Sasscer, Stiles,
Titus, and Webb, members, and Messrs. C. E. Burden, C. B.
Dyar, Dudley Moulton, and Dr. Reid Hunt, visitors.
Officers for the ensuing year were elected as follows: Presi-
dent, A. D. Hopkins; First Vice-President, O, Heidemann;
Second Vice-President, E. A. Schwarz; Recording Secretary,
W. F. Fiske; Corresponding Secretary, J. G. Sanders; Treas-
urer, J. D. Patten; members of the Executive Committee, in
addition to the officers, Harrison G. Dyar, L. O. Howard, and
C. L. Marlatt. Dr. A. D. Hopkins was nominated to repre-
sent the Entomological Society of Washington as a vice-presi-
dent of the Washington Academy of Sciences.
Mr. Webb exhibited a rare cerambycid beetle, Brothylus
conspersus Lec., collected by Mr. H. E. Burke in the Yosemite
National Park, Cal., the past season.
“Fred. W. Klages was the first naturalist of the family and one of
the pioneer entomologists of western Pennsylvania. He collected in
the South and in Jamaica and rediscovered and made known the habitat
of the hitherto exceedingly rare butterfly, Papilio homerus Fab. The
late Dr. John Hamilton, in his “ Catalogue of the Coleoptera of South-
western Pennsylvania,” gave his name as “ William,” an error until
now uncorrected.

—Mr. Burke showed a rather rare tussock moth from the
Yosemite National Park, Cal., Notolophus oslari Barnes.. He
stated that investigation proved to him that this species was
responsible for the bare tops frequently seen in that portion of
California in the California white fir (Abies concolor). From
larve kept under observation were reared Chalcis ovata Say,
Tachina mella Walk., and some braconids. A comparison of
the egg-masses of this species with those of three other well-
known tussock moths, namely, the white-marked tussock moth
(Hemerocampa leucostigma S. & A.), the gipsy moth (Por-
thetria dispar L.), and the rusty tussock moth (Notolophus
antiqua L.) is interesting; whereas the white-marked tussock
moth surrounds its egg-mass with froth, and the gipsy moth’s
egg-mass is covered with hair, that of Notolophus oslari is
surrounded with both froth and hair, while that of Notolophus
antigua is bare. Doctor Dyar stated that Notolophus oslari
was described from Colorado and this California record of
Mr. Burke was new; both the larva and the female were unde-
scribed. Mr. Burke stated that the larve strip the fir trees
from the top down for a distance of about 10 feet, thus destroy-
ing the seed crop. Doctor Howard suggested that Pimpla
inquisitor Scop. be introduced into California from the Eastern
United States to parasitize the Notolophus. Doctor Hopkins
said that he found Notolophus oslari ovipositing, in October,
1905, on the trunks and branches of fir trees which had been
defoliated by the larve, near Colorado Springs, Colo.,.and on
visiting the same locality the following June he found that the
eggs were hatching. Some of the egg masses were collected,
which later yielded a large number of egg parasites. Doctor
Howard remarked that these egg parasites found by Doctor
Hopkins might prove useful for introduction into the East to
combat the white-marked tussock moth, the gipsy moth, and
the brown-tail moth (Euproctis chrysorrhea L.).
Mr. Schwarz pointed out that this California record for a Colo-
rado species was an illustration of the fact that the faunas of the
eastern slope of the Sierra Nevada Mountains and the western
slope of the Rocky Mountains are closely related. The real
Pacific fauna is that of the Coast Range alone. Many persons,
144 ENTOMOLOGICAL SOCIETY
Mr. Schwarz said, erroneously considered the fauna of the
Rocky Mountains as radically different from that of the Sierra
Nevada. The faunas of the Wasatch Mountains of Utah—
a spur of the Rocky Mountain system—and that of the Sierra
Nevada in the vicinity of Lake Tahoe, California, are remark-
ably alike. There is in the U. S. National Museum a list of
Coleoptera collected by the late H. G. Hubbard on the Wasatch
Mountains, Utah, and another list of Coleoptera collected by
Mr. Hubbard in the same year at Lake Tahoe. A comparison
of these two lists would illustrate the affinities of the two
faunas. Doctor Hopkins then discussed the relation of bark-
beetles to the faunal regions of the eastern and western sec-
tions of the Rocky Mountain and Pacific Coast areas and the
evident value of these insects in defining local divisions and
sections of these regions as distinguished from those defined
by their host plants. He contended that in determining faunal
regions one should study groups of insects rather than single
species. Mr. Schwarz said that it was necessary to have expe-
rience to know what group to single out for study as aiding
in the determination of zoogeographical regions. As an in-
stance he cited the carabid genus Nebria as admirably adapted
for illustrating geographical distribution, not only as between
the Boreal and Transition zones, but also as between the Rocky
Mountain system and the Sierra Nevada.
—Mr. Busck showed some colored illustrations of Walker’s
types of Microlepidoptera prepared for the U. S. National
Museum by an artist in the British Museum.
—Doctor Howard mentioned a rather amusing incident in
connection with Mr. George Compere’s efforts to introduce
parasites of the codling moth (Carpocapsa pomonella L.) into
California from Europe. When the parasites arrived at their
destination no codling moth larve could be found to which to
transfer them, and larve had to be shipped in cold storage
from New Zealand to California to meet the emergency.
—Mr. Knab stated that he had come to the conclusion that
the character of toothed or untoothed claws in adult mosquitoes
would not define generic limits, for he had discovered that this
character is subject to variation, sometimes even within the
same species.
OF WASHINGTON. 145
—The first paper of the evening, an abstract of which fol-
lows, was by Doctor Howard:
POLYEMBRYONY AND THE FIXATION OF SEX.
By L. O. Howarp.
(Author’s Abstract.)
The speaker described his early observations on strange
methods of pupation among the Chalcidide (American Nat-
uralist, 1882; Insect Life, Vol. IV, 1891; and Proceedings of
the U. S. National Museum, 1892), indicating the existence
of certain unexplained phenomena in the development of cer-
tain hymenopterous parasites of the family Chalcididz, which
have subsequently been cleared up by the discovery of Marchal
of the existence of the extraordinary process known as poly-
embryony, by virtue of which from a single egg there may
come very many adult individuals. He reviewed the work of
Bugnion on the anatomy and habits of Encyrtus fuscicollis
(1891), a note by Giard (1898), and several papers by Paul
Marchal culminating in his startling work entitled Researches
upon the Biology and the Development of Parasitic Hymen-
optera—Specific Polyembryony or Germinogony (1904). He
further reviewed a paper by F. Silvestri entitled Contributions
to the Biological Knowledge of Parasitic Hymenoptera: (1)
Biology of Litomastix truncatellus (1906) ; and the admirable
summary of Marchal’s work by Bugnion, also published in
1906. The paper in full up to this point is published in
Science.*
The speaker then called especial attention to the extreme
interest attaching to further observations of this wonderful
life process, and dwelled upon the abundance of material for
study existing on every hand, the requirements for its inves-
tigation, now that the initial discoveries have been made, being
simply good laboratory facilities and a skilled technique to-
gether with trained powers of observation. These are to be
found with many institutions and many individuals in this
country, and there is every hope that before long the darkness
that has existed in our knowledge of the intimate early life
history of the parasitic Hymenoptera will be changed into the
bright light of accurate knowledge.
The speaker exhibited a large series of species of the encyr-
tid genera Copidosoma, Litomastix, and Ageniaspis, together
* Science, n. s., Vol. XXIV, No. 625, December 21, 1906, pp. 810-818.
146 ENTOMOLOGICAL SOCIETY
with a series of the distorted and cocoon-filled larve of their
hosts, showing that these insects had been bred from a large
series of lepidopterous larve of the tineine and tortricine series,
together with certain noctuids and pyralids. He also exhib-
ited one interesting specimen of a noctuid pupa—that of
Papatpema mnitela—which indicated that the larva, parasitized
by a multitude of Copidosoma larve, had succeeded in pupat-
ing before its destruction, the parasites having apparently been
unable to issue by perforating the tough integument but hay-
ing come out through an accidental break in the skin.
In discussing the possibilities of further discoveries, and as
indicating the most promising directions toward which inves-
tigations may be made, he stated that it is altogether likely
that all species of the genera Copidosoma, Litomastix, and
Ageniapsis will be found to have this method of development.
Copidosoma, as restricted, is well-known to be parasitic in
Europe and North America upon the larve of Microlepidop-
tera; Litomastix is known to be parasitic upon the larve of
Microlepidoptera, certain noctuid and geometrid larve, and
also upon cossids. Litomastix truncatellus, for example, is
known to be parasitic in the large wood-boring larva of Zeu-
zera escult, What an extraordinary opportunity for polyem-
bryony exists here, when we consider the immense numbers
of parasites which a full-grown larva of Zeuzera could harbor!
The genus Bothriothorax, the species of which infest large
dipterous larve and puparia—particularly the Syrphide and
the Anthomyiide—is a probable form. Homalotylus, which
produces the same inflated aspect with the larve of certain coc-
cinellids and chrysomelids, is another one; Dinocarsis, whose
only known host is Thyridopteryx, is still another; while all
of the lepidopterous parasites belonging to the old genus En-
cyrtus as listed by Dalla Torre are hopeful subjects for future.
investigation. Those forms infesting the smaller Coccide and
especially the Diaspine, may be shown to have the normal
development, but genera like Rhopus, certain species of Micro-
terys, Trichomasthus, Aphycus, Blastothrix, and Leptomastix,
which infest the larger scale insects and issue in considerable
numbers from a single individual, should be investigated, as
well as those parasites of the larger Coccide belonging to the
genus Encyrtus as listed by Dalla Torre.
In fact, the polyembryonic development is strongly to be
suspected in all cases where a minute hymenopterous parasite
infests in large numbers a host of large size, as occurs in many
groups of Chalcidide and Proctotrypide as well as in some
Braconide. Even in the familiar instance of Pteromalus
puparum, the common parasite of Pontia rape, and others. of
OF WASHINGTON. 147
the very numerous pteromalid parasites of larger Lepidoptera,
also with many of the forms of the family Eulophide as defined
by Ashmead, and especially perhaps in the subfamilies Ente-
doninz and Tetrastichine, and some at least of the Elachis-
tinz, we may hope to find this mode of development. We
have only to remember the manner in which a lepidopterous
chrysalis is sometimes packed with parasites of the genus Cir-
rospilus, or a large ichneumonid larva with Dibrachys, to see
the force of this suggestion.
Apanteles among the Braconidz also naturally occurs to
one, and the great number of larvze issuing from a large sphin-
gid larva is readily explicable by polyembryony, and this offers
an easy and important field of investigation. For many years,
the speaker said, he had had parasitized sphingid larve in dif-
ferent stages upon his desk awaiting the opportunity for dis-
section, but the chance had never come.
With the proctotrypids, Marchal has already shown us what
occurs with Polygnotus and also what is to be expected with
other forms of the subfamily Platygasterinze (and here the
speaker referred to a published announcement in the Bulletin
of the Entomological Society of France for October, 1906, of
the publication of Marchal’s paper upon this group) ; and other
subfamilies will bear investigation.
That polyembryony is a highly specialized function, and with
insects one of the concomitants of parasitism, seems likely. It
is therefore not to be expected in groups in which the parasitic
mode of. life is not old and firmly established for a very long
period of time. With the parasitic Diptera, therefore, where
from the non-specific character of the host relation it is to be
assumed that the parasitic mode of life is of comparatively
recent acquirement, polyembryony is not to be expected to
exist. The large number of Tachina eggs with which a lepi-
dopterous larva is frequently plastered is an indication of this.
;
In the discussion of the paper Mr. Reeves stated that he
had found larve of the Hessian fly filled with the parasitic
larve and pupe of Polygnotus, upon which the transparent
skin of the host larva had shrunken so as to lose its own form
and reveal nothing but the contained mass of parasites. The
largest number of parasites found in a single host larva was
41, the usual number ranging from 6 to 12. Doctor Stiles
remarked that the figures of Marchal were very suggestive of
148 ENTOMOLOGICAL SOCIETY
those illustrating the development of the malaria parasite and
that this polyembryony suggested the alternation of sexual and
asexual generations found in Protozoa and the trematodes.
As the rate of increase by the asexual mode is much more
rapid than that by the sexual mode it is fortunate for humanity
that in the case of the malaria parasite the period during which
reproduction can continue by the asexual mode alone is limited.
Certain phenomena resembling polyembryony, occurring in
other forms of animal life, were pointed out by various mem-
bers present, and Doctor Phillips spoke of the artificial produc-
tion of half and quarter embryos by chemical and mechanical
means and also referred to the work of Doctor Conkling on
ascidians, which seems to contradict the Mosaic theory of
development.
—Mr. Banks presented the following paper:
THE PSYCHODIDE OF THE VICINITY OF
WASHINGTON.
By NATHAN BANKS.
For several years I have taken some interest in collecting
the Psychodidz wherever I have resided, and have now a dozen
species from the vicinity of Washington, four of which are
new. These tiny, delicate flies are not easily preserved for the
cabinet; it is necessary that they be mounted soon after cap-
ture, and that no other insects be in the vial with them; so
. that unless one goes especially prepared to catch them, his
captures will not be worth much.
I have not had the facilities to attend to the rearing of any |
of the species, but offer notes on the habits and habitats of
some of the forms. I am inclined to think that most of our
species do not live in water, but only in moist places.
Psychoda alternata Say.
Our most common species, taken in June, July, August, and
November. It is often found resting on out-buildings, and
doubtless breeds in muddy spots adjoining them.
Psychoda cinerea Banks.
Occurs on manure in the fields and woods, often far from

Head black, some whitish-gray hair above; antenne dark brown,
tapering; thorax black, densely clothed with whitish-gray hair above,
and jet-black hair behind near the abdomen; the latter black, with
mostly black hair, a streak of whitish hair each side toward tip; legs
blackish, the tarsal articles white at the tips. Wings with grayish-
white hair on basal part along the second vein, and near the anal
margin; on the basal part are four tufts of erect jet-black hair, one
near costal margin near base, one on anal margin at end of whitish
hairs, and two on the discal part of wing just before the middle; costal
fringe long, jet-black, interrupted just beyond the middle and just
before the tip by patches of snow-white hair, two similar patches in

One specimen from Falls Church, Va., 15 May. A very
handsome species.
Psychoda interrupta, n. sp. oo
Head and thorax densely clothed with whitish hair above, some gray
on the middle of the thorax; antenne with gray hairs, tapering;
abdomen black, some white hair each side at tip; legs pale, marked
toward the tips with blackish, the hind tibia blackish at tip, the basal
and apical tarsal joints mostly black. Wings gray on basal part, with
few hairs, more densely haired on apical part and more or less dark
brownish, in some specimens a faint appearance of three dark bands,
one apical, one at middle, and one near base; costal fringe gray, white
near tip; apical fringe snow-white, at outer anal angle a broad patch
of black fringe, basad of it is white, and then brownish. In the apical
part of the costa in well-marked specimens, are three small white spots,
slightly indenting the wings from the costal margin.
Expanse, 2.4 mm.
Several specimens from Plummers Island, Maryland, 24
July, 28 August, attracted to the light.
Psychoda basalis, n. sp.
Head and thorax with brownish hair, a prominent tuft of white hair
on face; antenne black; thorax rather yellowish brown; abdomen
black, with black hair; legs black, with some scattered white hairs,
rather longer than usual. Basal half of wing jet black, made so by
densé hairs from the veins, a tuft of gray at extreme base; beyond the
middle of wing the hair is grayish and sparse; basal, costal, and poste-
. rior fringes black, apical fringes less dense and grayish, although the
extreme tip is jet black. Allied to P. bicolor Bks., but distinct by
dark gray hair on thorax (white in P. bicolor), and by darker legs, etc.

Expanse, 3.5 mm.
One specimen from Falls Church, Va., 17 July.
Mr. Knab spoke of the finding, by Mr. J. B. Van Duzee,
of a psychodid larva in water between the leaves of a Bromelia
in Florida. The adult, on examination, seemed to be a new
species. Another psychodid larva he himself found to be very
abundant in moisture at the margin of a sewer outlet in Mex-
ico. Mr. Barber referred to his former note before the Society
(see p. 102) on a blood-sucking psychodid, Flebotomus sp.,
found in Guatemala, and stated that a species of Flebotomus,
had lately been discovered by him at Plummers Island, Mary-
land, and that this species had the same annoying habit.
